Diddy Kong

Diddy Kong, also known as Diddy, is Donkey Kong's little buddy who has gone on countless adventures with him. Diddy Kong is a creation of the British company, Rare Ltd.; however, he has a Nintendo logo on his trademarked red hat.

The name "Diddy" is a slang word used in some parts of northern England for "small", as Diddy Kong is. Diddy Kong has gone on many adventures by himself, occasionally with his girlfriend Dixie Kong, and has even starred in his own racing game for the Nintendo 64 and later in the remake for the Nintendo DS.

Concept and creation
During the development of Donkey Kong Country, the designers wanted the player to be capable of taking multiple hits, but they also aimed for the screen to be as "clutter-free" as possible, thereby forbidding the usage of a health bar. Having noted the "Big Mario to small Mario" system used in the Super Mario games, Rare created Diddy Kong as a visual "extra hit". The design for the character was originally intended to be a redesign of Donkey Kong Jr., but Nintendo felt that their design was too different, and asked that Rare either include Junior with his original appearance or make the new design an entirely different character. Rare, feeling that the design fit the "updated" Donkey Kong universe that they were aiming to create, had decided to keep their design. During the process of naming the character, several names were suggested by Rare employees, including "Diet DK," "DK Lite" and "Titchy Kong". The name "Dinky Kong" was chosen, but was later changed to "Diddy" due to legal considerations, although the name would eventually be used as Kiddy Kong's Japanese name.

Donkey Kong Country
Diddy Kong first appears in Donkey Kong Country, as the co-star of the game with Donkey Kong. Here, he is still Donkey Kong's apprentice and an "in-training video-game star". On one night, Diddy Kong is given the task of guarding Donkey Kong's Banana Hoard. However, the Kremling Krew attacks and defeats him, trapping him inside a barrel. After being released, he and Donkey Kong set off across Donkey Kong Island to save the Banana Hoard and drive off the Kremlings. At the end of their journey, Donkey Kong and Diddy Kong reach King K. Rool, the leader of the Kremlings, and by defeating him, the two win back Donkey Kong's Banana Hoard.

In this game, Donkey Kong and Diddy Kong share the same basic abilities (jumping, running, cartwheeling, etc.). However, Diddy Kong is weaker than Donkey Kong, unable to jump on enemies such as Krushas or Klumps to defeat them, but Donkey Kong can. Despite this flaw, Diddy Kong is still faster than him and can jump higher than him. Diddy Kong also carries barrels in front of him, allowing him to protect himself from an enemy, but he cannot throw it as far as Donkey Kong.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Diddy Kong is the main hero. The Kremling Krew kidnaps Donkey Kong and sends him away to their own island, Crocodile Isle. K. Rool, who is now Kaptain K. Rool, threatens to permanently hold Donkey Kong prisoner unless he is given the Banana Hoard. Diddy refuses to give it up because he and Donkey Kong took plenty of effort recovering it in the previous game. Diddy and his girlfriend, Dixie Kong, venture through Crocodile Isle and rescue Donkey Kong from Kaptain K. Rool. Near the end of Diddy's Kong Quest, while Donkey Kong is rescued by Diddy Kong and Dixie Kong, Crocodile Isle sinks into the ocean.

Donkey Kong Country 3: Dixie Kong's Double Trouble!
Diddy Kong is captured in Donkey Kong Country 3: Dixie Kong's Double Trouble!, and Dixie Kong and Kiddy Kong must save him. Diddy and Donkey decide to go vacationing in the Northern Kremisphere, planning to return to Donkey Kong Island in a few days time, but the duo never comes back. Dixie, worried about the two Kongs, decides to venture to the Northern Kremisphere to search for them with her baby cousin Kiddy Kong. After Dixie and Kiddy defeat Baron K. Roolenstein they discover that KAOS, K. Rool's stand-in leader for the Kremling Krew, contains Diddy and Donkey. It seems K. Rool has abducted Diddy and Donkey for the purpose of using their brain energy to power KAOS. After being rescued Diddy and Donkey goes back to Donkey Kong Island while Dixie and Kiddy defeat the Kremling Krew.

Donkey Kong Country Returns
Diddy Kong appears in the Wii game, Donkey Kong Country Returns and the 3DS remake Donkey Kong Country Returns 3D. He is the first to notice the Banana Hoard being stolen by animals who are hypnotized by the Tiki Tak Tribe, and attempts to pursue them to retrieve it. However, Diddy fails, and he is shoved into a barrel. After he is freed, he and Donkey Kong go on another quest to reclaim the Banana Hoard by traversing through the various regions of the islands while fighting the operatives in each of them. After defeating Tiki Tong, he and Donkey Kong get the Banana Hoard back from the Tiki Tak Tribe.

Diddy has different roles after the final battle. If he's with his big buddy at the end, they are ejected from the lair by the explosion of Tiki Tong to space. While Diddy panics, DK comes up with a plan and they knock the moon out of its orbit. Even without Diddy, Donkey Kong still frees the bananas, only to realize he's falling at alarming speed. Fortunately, Diddy Kong returns to save his friend. Should Diddy triumph on his own, he tries to break free from the moon's gravitational pull with his barrel jet. However, it malfunctions and he crashes headfirst into the moon, the impact knocking it out of orbit. The unconscious Diddy plummets from the sky, only to land and awaken in DK's hands. Either way, the Kongs celebrate at bananas' freedom.

Diddy can be controlled in this game by a second Wii Remote. He's more agile than Donkey Kong, and still has control of the barrel jet. He also has Peanut Popguns which can be used to stun enemies (and gain an edge on Mugly and Thugly).

Donkey Kong Country: Tropical Freeze
Diddy Kong appears as one of the playable characters in Donkey Kong Country: Tropical Freeze. He can be found inside barrels marked with a blue "DD". He retains his ability to use his jetpack to hover as well as the Peanut Popgun from Donkey Kong Country Returns. When with Diddy, all enemies affected by his Kong POW are turned into red Extra Life Balloons and DK gets a speed boost from his barrel jet.

Diddy was celebrating DK's birthday along with him, Dixie, and Cranky until the Snowmads came along and blew them away from the island to claim it. Diddy then helps his friends get back home and retake it.

"Donkey Kong Country"
Diddy also appears in the Club Nintendo comic "Donkey Kong Country", serving a similar role to the one in the game of the same name. Diddy's task is to watch over the Banana Hoard. However, King K. Rool finds him and puts him into a Barrel. Donkey Kong soon discovers him, and they track down King K. Rool to defeat him.

"Super Mario in Die Nacht des Grauens"
In comic "Super Mario in Die Nacht des Grauens", published in the same magazine, Diddy Kong lives in a skyscraper in Brooklyn with many other Nintendo characters. Due to a contract signed by Wario, the skyscraper is invaded by several monsters. One of them, Chuckie, invades the Kongs' room while Diddy and Donkey are watching TV. They are terrified by the evil doll, but they are rescued by Mario, Link and Kirby.

"Donkey Kong in: Banana Day 24"
Diddy makes another appearance in the Club Nintendo comic "Donkey Kong in: Banana Day 24". The Kongs have to save the world from freezing, since a giant U.F.O, is pulling the Earth away from the sun. With Donkey, Dixie, Kiddy and Cranky, Diddy enters a space shuttle and flies into space to talk to the aliens. As it turns out, the reason for them pulling away the Earth is that they mistook the planet for a giant coconut. Diddy finds a solution to this problem by giving bananas to the aliens, and in return they promise to return the Earth to its original position.

Super Mario-Kun
Diddy Kong appears in the fourteenth volume of the Super Mario-Kun manga comics. Even though a majority of the volume is based on Super Mario World 2: Yoshi's Island, the end of it contains Donkey Kong Country and Donkey Kong Country 2: Diddy's Kong Quest content. In the Donkey Kong Country part of the volume, Cranky Kong asks Diddy and Donkey Kong to battle King K. Rool. He also appears with his girlfriend, Dixie Kong to battle Kaptain K. Rool in the Donkey Kong Country 2: Diddy's Kong Quest part.

Donkey Kong Country: Rumble in the Jungle
In the 1995 children's novel Donkey Kong Country: Rumble in the Jungle, Donkey Kong introduces his "buddy" Diddy Kong to Funky Kong, who offers Diddy a ride in his barrel plane around Donkey Kong Island. During the flight, Diddy Kong notices smoke coming from Big Ape City, which was believed to have been abandoned. Hoping for an adventure, he is willing to investigate, although Funky Kong prefers to not "go looking for trouble". Returning to his treehouse after the flight, Diddy Kong realizes that he still has Funky Kong's walkie talkie, and trying to contact him reveals that his plane is being attacked by "flying pigs" over Big Ape City. Diddy Kong immediately agrees to travel with Donkey Kong to the city, joined by a reluctant Cranky Kong.

On the edge of the forest in Tree Top Town, the Kongs encounter a group of Kremlings. Diddy Kong performs several cartwheel attacks, which is true to his abilities as a playable character in the Donkey Kong Country and Donkey Kong Land series of games. Upon reaching Big Ape City, Diddy Kong is eager to find a way to infiltrate the factory, despite the high numbers of Kremling security guards. Overhearing some guards speaking, the Kongs discover that Funky Kong is being kept in the factory. After locating and breaking open Funky's cell, Diddy Kong assists Donkey Kong in clearing some Kremling guards using barrels. Upon inspecting his damaged plane, Funky draws a map for Diddy, explaining where to find the factory's supply room for a replacement waterpump. Diddy Kong traverses over several catwalks to reach the store room, where he encounters a Klap Trap. Diddy Kong lodges a barrel into the Klap Trap's large mouth, allowing him time to escape with the water pump.

After the Kongs from the factory in the barrel plane, Donkey Kong has the idea to jump from the plane and onto King K. Rool's zeppelin. Although afraid, Diddy Kong joins him in entering the zeppelin and defeating several Kremlings using cartwheels, double jumps and barrels. Afterward, Donkey and Diddy Kong plant the airship with time-delayed TNT Barrels, and choose to let the "coward" King K. Rool to escape. After re-entering the plane, Donkey Kong compliments Diddy Kong on how well he fought the Kremlings, and all the Kongs share a laugh as they watch the planted TNT Barrels explode onto the Kremling's factory.

Rool steals Donkey Kong's Banana Hoard and kidnaps several Kongs, with Diddy being one of them.

From then on Diddy aids Donkey and the other Kongs with shutting down the Blast-o-Matic and getting rid of King K. Rool by collecting red bananas and coins and using his abilities gained from Cranky, as well as his electric guitar from Candy and his popguns from Funky. Eventually K.

Super Smash Bros. series


Diddy Kong joins the Super Smash Bros. series in Super Smash Bros. Brawl and returns in Super Smash Bros. for Nintendo 3DS / Wii U. He is swift, agile, and very acrobatic, just like how he is in the Donkey Kong series.

Diddy Kong's special moves are Peanut Popgun, which lets him shoot peanuts at his opponents, Monkey Flip, which lets him leap forward and pummel his opponents, Rocketbarrel Boost, which can be charged to fly through the air, and Banana Peel (move), which when thrown makes his opponents slip and fall. His Final Smash is Rocketbarrel Barrage, and it combines two of his special moves, Peanut Popgun and Rocketbarrel Boost, together. Diddy Kong is the first character to represent the Donkey Kong series in a Super Smash Bros. game since Donkey Kong himself. While Diddy Kong does not appear in Super Smash Bros. and Super Smash Bros. Melee in any capacity, he is mentioned in both games. Diddy Kong was revealed for Super Smash Bros. for Nintendo 3DS / Wii U on February 21, 2014, the day of the North American/European release of Donkey Kong Country: Tropical Freeze. Early on in the game's lifetime, Diddy became notorious in competitive play for his very powerful and easy-to-use throw combos, leading to some of his moves being slightly weakened in later balance patches. Diddy Kong is set to reappear as a playable character in Super Smash Bros. Ultimate.

For the Super Smash Bros. series, Diddy is given a more realistic monkey voice, instead of the cartoonish voice he is commonly given in Mario series titles.

Owing to King K. Rool's ties to Donkey Kong, Diddy Kong appears alongside Donkey Kong in K. Rool's debut trailer for Super Smash Bros. Ultimate. Specifically, Diddy Kong lounges lazily in Donkey Kong's tree house on a tire swing, only to be startled by quakes before looking outside with Donkey to investigate. They then see an ominous and familiar shadow, only for it to be revealed to be King Dedede wearing a cape and King K. Rool's mask, to their surprise. King Dedede then proceeds to laugh at the practical joke he played on them, only for him to be smacked upside the head and knocked away by the actual King K. Rool, much to Diddy and Donkey Kong's horror, with King K. Rool roaring. In the ending of the trailer, Diddy, alongside Donkey Kong, has their foot and fist, respectively, make contact with King K. Rool's fist with enough force as to cause a shockwave to be emitted throughout the jungle.

The Subspace Emissary
In the Jungle, Diddy Kong helps Donkey Kong recover bananas stolen from the Koopa Troop, only to have Bowser appear and attempt to use his Dark Cannon on the Kongs. Donkey knocks Diddy away to safety before anything happens, however, although at the cost of Donkey Kong being turned into a trophy in the process. At the Lake, Diddy encounters Rayquaza, teams up with Fox McCloud by force, and fights False Bowser, but they end up fleeing from the real Bowser. As they reach the Swamp, Bowser successfully attacks Diddy, turns into a static trophy and clones him into False Diddy Kong with shadowbugs. After Diddy is revived, he defeats the clone and teams up with Falco Lombardi, again by force.

Upon discovering that Donkey is being taken to the Island of the Ancients, Falco drops Diddy for the little Kong to rescue him. After receiving help from Captain Falcon and Captain Olimar to fend off the Subspace Army, all four of them end up at the Subspace Bomb Factory. Upon meeting Samus and Pikachu, R.O.B. reveals himself just before they are forced to evacuate the island as it is sucked into Subspace.

In Subspace, Tabuu turns all of the gathered heroes, including Diddy, into trophies. However, Diddy is among the fighters rescued by King Dedede and his team before they all head into the Great Maze to defeat Tabuu and save the world, with help from Sonic the Hedgehog.

Mario Sports Mix
Diddy Kong appears in Mario Sports Mix as a playable character. He is a speedy character that has a slightly higher technique stat countered with a slightly lower power stat, along with other three speedy characters, Bowser Jr., Toad and Cactuar. His Special Shot has him throwing a banana that acts like a boomerang, attempting to stun any players that try to counter his shot.

In Volleyball, Diddy Kong can give his full power shots an added curve, which is something that is typically seen with the Technical characters.

Fortune Street
Diddy Kong appears as a playable character in the Wii follow-up to Itadaki Street DS, Fortune Street. He is a Level D character, alongside Birdo, Donkey Kong, Slime and Yangus.

Super Mario Maker
While one is playing Super Mario Maker, one can place Diddy Kong's amiibo onto the Wii U GamePad and scan it to reveal a Mystery Mushroom in the game. This mushroom offers the player's character the possibility to transform into Diddy, once it is collected. Diddy Kong is only rendered in 8-bit, since it is only possible to play as him in the Super Mario Bros. style of the game. His motion is based on the one from Donkey Kong Country, whence he comes from.

Mario Sports Superstars
Diddy Kong appears as a starter, playable captain-type character in Mario Sports Superstars. Through most sports, he is a Speed type character, sharing the quality with Baby Mario, Baby Luigi, and Bowser Jr. In golf, his default drive is 216 yards, and his shots travel slightly high in a draw trajectory.

Other appearances
Diddy was to star in both Diddy Kong Pilot and Donkey Kong Racing as a main character and a sidekick, respectively, but these games were canceled before they could be released when Rare Ltd. moved to Microsoft.

In 1998, despite not yet being part of the Mario series, he was featured alongside Mario, Yoshi and Koopa Troopa in a dispenser set. Diddy Kong also appears in Nintendo Monopoly, where he costs $260, and took the role of Ventnor Avenue.

The 2009 WiiWare game WarioWare: D.I.Y. Showcase featured a microgame entitled DK Country, which is based after the Game Boy Advance version of Donkey Kong Country 2. The player takes control of a moving Bonus Barrel, from which Diddy gets shot into the air. The monkey must avoid an energic red Zinger and collect two rows of bananas, in order to win the game.

Diddy Kong appears in the game Skylanders: SuperChargers as part of the SuperCharged version of Donkey Kong's vehicle, the Barrel Blaster. He's also the basis of Donkey Kong's Soul Gem Diddy You Call?, where after being summoned he can fly around in his Rocketbarrel Pack and attack enemies with his Peanut Popguns, similar to his Final Smash from Brawl and Smash 4.

In the Super Mario Mash-Up Pack in Minecraft, Diddy Kong appears as a playable skin. In Super Mario Odyssey, one of the billboards in New Donk City mentions a "Diddy's Mart". Diddy's outfit also appears as a purchasable costume for Mario after completing the game and collecting enough Power Moons.

Diddy Kong is a playable character in Monopoly Gamer. He is sold separately as a "Power Pack" expansion figure.

Physical appearance
Diddy Kong shares several traits to a. He has versatile feet, and a prehensile tail (the only Kong to possess one), which he uses most of the time to hold certain small items or also hang on objects. Diddy Kong's face is somehow similar to Donkey Kong; however, Diddy Kong has big eyes and a less frowned space between the eyebrows, covered in fur, as opposed to Donkey Kong's. His ears are a bit big, the same size of his eyes. Diddy Kong's eyes are usually depicted as black, although Diddy Kong Racing and Donkey Kong 64 reveals blue eyes. On the other hand, Super Smash Bros. Brawl gives him brown eyes. The color of his eyelids varies depending on his appearances; sometimes they are either brown (like in Donkey Kong 64 and Diddy Kong Racing DS) or tan (like in Donkey Kong Country, Donkey Kong Country 2: Diddy's Kong Quest and the Super Smash Bros. series) and mostly he has no eyelids at all (though he still blinks but his eyes remain open).

Diddy Kong's clothing consists of a red cap showing the logo of Nintendo on its front, and a red tank top, with yellow Stars on it (the details on his clothes were first introduced in Donkey Kong Country 2: Diddy's Kong Quest). In Donkey Kong Country, an alternate Diddy Kong's clothing was a yellow tank top and a yellow cap. It appeared when two players wished to play independently. In Donkey Kong Country 2: Diddy's Kong Quest, Diddy Kong appears with another alternate costume as well. In the sequel, Diddy Kong wears a blue costume. For the recent edition of Super Smash Bros. series, Diddy has a wider selection of alternate color costumes. In Mario Strikers Charged, Diddy Kong wears armor, protecting him against hazards set in the game. He wears a pair of wristbands, shoulder-pads, and a cuirasse over his tank top to protect his chest. The armor is mainly yellow, but it turns to purple in case that his opponents wear a similar color scheme. Later in Donkey Kong Country Returns, when the Super Guide mode is activated and Super Kong breaks a DK Barrel open, Super Diddy Kong appears. Super Diddy Kong has white fur, a white cap, and a blue tank top.

Speech
In the early Donkey Kong Country games, as well as the Donkey Kong Land series, there wasn't any voice acting, though Diddy Kong did have a few realistic monkey sounds. However, the games' respective instruction manuals showed Diddy Kong being able to speak full sentences. Diddy Kong was able to speak intelligently in the comic Rumble in the Jungle and the Super Mario Kun manga. Diddy Kong first received voice acting in the 1998 computer-animated Donkey Kong Country series, where he was portrayed by Andrew Sabiston. In the GameCube-era Mario and Donkey Kong games, Diddy was voiced by Chris Sutherland, who provided him with a mixture of cartoonish monkey noises and actual words/phrases, such as "Come on!" From 2007 onwards, Diddy Kong has been voiced by Katsumi Suzuki, who solely provided him with a cartoonish monkey voice. In cases where Diddy Kong is intended to speak in full sentences, there is in-game text to show what he is actually saying. Most of the time, his speech is in parentheses, thus implying that characters other than Donkey Kong still have difficulty understanding what he is saying. In the Super Smash Bros. series, Diddy Kong receives realistic chimpanzee noises.

Powers and abilities
In almost every appearance he makes, Diddy Kong has been shown to be very quick and nimble to offset Donkey Kong's great strength. As a result, Diddy has more trouble defeating larger enemies. In many games he has appeared, such as in Donkey Kong Country and Donkey Kong 64, he is able to use his cartwheel to attack opponents but also to jump farther in Donkey Kong Country. Diddy Kong is shown to have a strong skull; he has a special dashing ability in Donkey Kong 64 called Chimpy Charge where he ram into switches, walls, and gongs with a head-first charge and in Donkey Kong Country Returns, after defeating Tiki Tong, he brings the moon down with just his head.

While teamed up with Dixie Kong during the events of Donkey Kong Country 2: Diddy's Kong Quest, Diddy Kong is able to pick up his partner and throw her to high areas or enemies. He can also throw her at collectibles that float above pits.

In some games, Diddy Kong can also use his Jetpack to fly to hard-to-reach areas. However, in Donkey Kong 64, this Jetpack is only given to him after entering one of Cranky's Kong Barrels, and it can only be used in certain areas. During the time Diddy Kong uses his Jetpack, he is also equipped with Peanut Popguns, which allow him to defeat or stun distant enemies and activate switches. During Donkey Kong Country Returns, Diddy Kong can use his Jetpack in order to carry Donkey Kong over pits. It's revealed in Donkey Kong Country 2: Diddy's Kong Quest, that Diddy Kong has a prehensile tail due to the fact he can hang onto hooks with it. Additionally, in Donkey Kong 64 he is able to use his tail to attack enemies or use it as a spring to reach higher areas. In Super Smash Bros. Brawl, he is able to combine his Jetpack and Peanut Popgun for his final smash. He can also perform Wild Moves in Donkey Kong Barrel Blast.

In Mario Superstar Baseball, Diddy Kong, with his good running stat, also possess the ability to climb on walls and catch balls that are otherwise fair. He also has Super Catch ensuring that he does not fumble any routine fly balls. His pitches and batting involve curving the ball in the shape of a banana. This ability is also present in Mario Power Tennis. In Mario Striker Charged, Diddy Kong displays some supernatural abilities such as summoning a beam of light that subdue his opponents into the sky and psychic abilities during his Mega Strike. In Mario Sport Mix, his special move is throwing a banana like a boomerang which stuns opponents after being hit by it.

Diddy Kong is capable of juggling, which he does in Donkey Kong Country 2: Diddy's Kong Quest if he does not move for a while. Also, his artwork for Mario Super Sluggers portrays him juggling three baseballs. Just like Dixie Kong in Donkey Kong Country 2: Diddy's Kong Quest, he is also capable of playing an electric guitar in Donkey Kong 64, which he uses to solve puzzles and destroy surrounding enemies.

Personality
Diddy Kong is a kind and adventurous character who is willing to help out his friends Donkey Kong, Dixie Kong, and Cranky Kong during times of need, evidenced by the Donkey Kong Country series. Diddy Kong is somewhat of a peace seeker, which is an offset to Donkey Kong's more aggressive behavior against his enemies, since he asks a Kremling to "show himself if he was friendly" in Donkey Kong Country 2. Diddy Kong's defining personality trait is his energy and gaiety, to the point of childishness (in a similar vein to Toad, though he is less humble than the mushroom himself). Diddy Kong always shows excitement in various competitive sports (the Mario Golf, Mario Tennis, and Mario Baseball series) and kart races, as evidenced by his idle and victory animations, which see him cartwheeling, backflipping, sideflipping, jumping up and down, or clapping his hands while yelling and screeching in happiness and enjoyment. Diddy's boisterous, slap-happy personality comes into play in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, where he's constantly smiling or showing toothy grins. Diddy Kong's victory animations show him holding his head with both his hands, or firing a peanut from the Peanut Popgun, further showing how excitable he is. However, despite his energetic, excitable nature, Diddy Kong becomes sad when he loses to a boss in the Donkey Kong Country games or his opponents in various Mario spin-offs and Super Smash Bros. games, thus showing that he doesn't like to face defeat.

Friends
Donkey Kong is Diddy Kong's best friend and idol. Diddy Kong does not appear to be related to Donkey Kong since they are different species, but he has been called Donkey Kong's nephew on occasion, such as in the English version of Super Smash Bros. and once on Rare's website; however, the Japanese version of Super Smash Bros. did not call him DK's nephew, Leigh Loveday himself uses uncertain language, and the Donkey Kong 64 instruction booklet only considers him "Donkey's little nephew wannabe." The idea was soon dropped, and the usual story returned to them just being close friends.

Cranky Kong considers himself to be a "grandpappy" of sorts to Diddy Kong (as well as Dixie Kong), and while he complains about Diddy Kong receiving a starring role in Donkey Kong Country 2: Diddy's Kong Quest while he was stuck in a gloomy shed, he also calls him a true video game hero and comments that he must take after himself and Donkey Kong.

Dixie Kong has accompanied her boyfriend Diddy Kong on a few adventures and sports outings, including Diddy Kong Racing DS, in which Donkey Kong did not appear. Their romantic relationship is not often touched upon in the games themselves.

Official profiles and statistics
Diddy Kong is usually introduced as Donkey Kong's buddy in his official bios, with Dixie Kong being mentioned occasionally as well. He is typically described as being small and agile, and his stats in most spinoffs accordingly make him a lightweight and/or speed character.
