Donkey Kong Country 2: Diddy's Kong Quest

Donkey Kong Country 2: Diddy's Kong Quest is the second installment of the Donkey Kong Country series. It was developed by Rareware and published by Nintendo for the Super Nintendo Entertainment System. It is a sequel and direct follow-up of Donkey Kong Country; the game stars Diddy Kong, as he and his girlfriend, Dixie Kong, make their way through Crocodile Isle to save Donkey Kong from the Kremling Krew.

In 2004, a remake of the game was made for the Game Boy Advance. It features several differences, including the addition of photographs and extra Cranky's Video Game Hero Coins. It omits the Diddy's Kong Quest subtitle, thus the game is simply known as Donkey Kong Country 2.

In 2007, the original Super Nintendo version was re-released on the Wii's Virtual Console. On November 25, 2012, for reasons unknown, Donkey Kong Country 2 and the other two original Donkey Kong Country titles were delisted from the Wii Virtual Console; on October 30, 2014, the games were relisted in Europe and Australia. Around the same time, Donkey Kong Country 2: Diddy's Kong Quest was released for the Wii U Virtual Console in Europe and Australia in October 2014, and in the United States and Canada in February 2015. For handhelds, the game was ported exclusively to the New Nintendo 3DS Virtual Console in 2016.

Donkey Kong Country 2: Diddy's Kong Quest is the sixth best-selling Super Nintendo Entertainment System game, with its predecessor being the third. A similar Game Boy title was released a year later, in 1996, Donkey Kong Land 2.

Story
"Arrrrgh! This story's even worse than DKC! They're really scraping the bottom of the barrel this time!"

- Cranky Kong

Some time after the events of Donkey Kong Country, Donkey Kong is relaxing at a beach, sitting on a chair while drinking a banana milkshake. Funky Kong is busy surfing waves among the seagulls. Cranky Kong walks up to Donkey Kong and hits him on the head with his cane. Cranky asks Donkey Kong why he is sitting around if he's a "big star". Donkey Kong replies that even stars need time off. Cranky says he never took breaks, "whisking off maidens and throwing barrels seven days a week". Donkey Kong asks Cranky to leave him alone and stop pestering him, so Cranky leaves. Donkey Kong then goes to sleep in his chair.

At night, Diddy Kong and Dixie Kong are worried because Donkey Kong has not returned. They go to the beach to investigate, and the Kongs find many footprints surrounding Donkey Kong's broken chair. They find a note in the chair which reads:


 * Hah-arrrrh! We have got the big monkey! If you want him back, you scurvy dogs, you'll have to hand over the banana hoard! Kaptain K. Rool

Cranky suggests handing over the banana hoard to K. Rool. Diddy refuses because of how much effort he and Donkey Kong went through to retrieve the bananas, and that Donkey Kong would be very upset if his bananas were stolen again. Cranky asks if they have any better suggestions, and Diddy and Dixie both say that they want to rescue Donkey Kong themselves. The two get in a brief argument with Cranky, who does not believe Diddy qualifies as a video game hero. Diddy vows to return with Donkey Kong, and together, he and Dixie, who insisted on joining, start their journey. The two Kongs travel through Crocodile Isle, the hometown of the Kremlings. They defeat numerous enemies and collect items on their way. Diddy and Dixie first travel aboard Gangplank Galleon, a large pirate ship docked at the coast. After completing the world, Diddy and Dixie move on to the volcanic world, Crocodile Cauldron, then the swampy Krem Quay, then the abandoned amusement park Krazy Kremland, and a spooky woods, Gloomy Gulch. Diddy and Dixie eventually reach the end of the sixth world, K. Rool's Keep, where they find Donkey Kong tied up in a chamber. Just as they celebrate, Donkey Kong is pulled up into K. Rool's personal airship, The Flying Krock.

Aboard the giant airship, Diddy and Dixie find Donkey Kong tied up, and they battle Kaptain K. Rool. Donkey Kong eventually breaks free from his ropes, and he uppercuts K. Rool out of the roof. Kaptain K. Rool falls all the way down Crocodile Isle and into the surrounding water, where he is seemingly eaten up by sharks.

During their adventures, Diddy and Dixie can also enter the Lost World by paying a Kremkoin fee to Klubba at his kiosk. The Kongs eventually enter Crocodile Isle's power source, Krocodile Kore, where they re-encounter Kaptain K. Rool. After a short battle, K. Rool's blunderbuss explodes, which propels him into the energy geyser powering Crocodile Isle. This blocks the power flow, which then destroys Crocodile Isle.

From a cliff, Donkey Kong, Diddy, and Dixie watch as Crocodile Isle explodes while sinking into the ocean. Just before the isle sinks, K. Rool escapes on a boat, laughing as he sails off into the horizon.

Abilities
Donkey Kong Country 2: Diddy's Kong Quest is a 2D platformer like its predecessor, Donkey Kong Country. The player controls Diddy Kong and Dixie Kong, whose basic abilities include jumping, climbing, and swimming. The Kongs usually jump to cross gaps and grab airborne items. Either Kong can perform a mid-air jump if they cartwheel or spin off a nearby ledge, often necessary for reaching secret areas or collectibles. Like Donkey Kong Country, Diddy can perform a cartwheel attack and still retains his agility (he can jump, climb, run, and swim a bit faster than Dixie). Dixie's equivalent to the cartwheel attack is the Helicopter Spin, where she spins into an enemy. Dixie has the advantage of also being able to perform the ability in mid-air, where she whirls her ponytail to glide to nearby areas or to cross some large gaps. There are more enemies that Diddy and Dixie can defeat by their respective cartwheel or spin attack, rather than a jump attack.

If both Kongs are on screen, they can perform Team-up, where either Kong piggybacks on the other in front. While this slows Diddy and Dixie's movement, either Kong can be thrown to reach items or higher areas. When a Kong is thrown to a higher platform, the lead Kong automatically moves up there with them.

Diddy holds a carriable object in front of him, which includes Barrels, Crates, and Treasure Chests. This way Diddy can defeat an enemy who walks into the object. Dixie holds an object over her head with her ponytail, and this still leaves her vulnerable to attack.

The swimming mechanic is similar to earlier Super Mario platformers. The player must hit, the jump button, to advance upwards into the water. If the player does not press the button, the Kongs slowly float to the bottom. Pressing enables them to descend quicker.

Modes
When starting a new file, the player has the option to choose between one or two player modes. The original Super Nintendo version has two hidden modes which can be accessed by pressing Down on the a number of times.

Bonus Games
The Game Boy Advance version features three minigames (more specifically, Bonus Games), which can be accessed from the "Bonus Games" option of the selection menu. The minigames are also in the Kongs' adventure and are hosted by a supporting character. It also includes a time attack mode, which is somewhat a successor to DK Attack from the Game Boy Advance remake of Donkey Kong Country.

Diddy's Dash
The Game Boy Advance version has a time attack mode titled Diddy's Dash, just as Donkey Kong Country's Game Boy Advance remake had DK Attack. The player only controls Diddy, who must complete each level as quickly as possible while being tracked by an on-screen timer.

Playable characters
The game has two main playable characters who work together to save Donkey Kong from the Kremlings.

Supporting characters
Diddy and Dixie are assisted by four members of the Kong Family, two of whom return from Donkey Kong Country and two who debut in the game. There is one Kremling who acts as a supporting character.

Animal Friends
Animal Friends are animals who help Diddy and Dixie on their quest. Each Animal Friend has its own abilities, which helps the Kongs find Bonus Barrels, Cranky's Video Game Hero Coins, Banana Coin, and other collectible items. There are a total of nine Animal Friends, a few of them return from Donkey Kong Country. Donkey Kong Country 2: Diddy's Kong Quest has the most Animal Friends compared to other titles in the Donkey Kong Country series.

Enemies
The game features a handful of enemies, many of whom are Kremlings. Most of them first appear in Donkey Kong Country 2: Diddy's Kong Quest, though a few of them return from Donkey Kong Country.

Bosses
Like Donkey Kong Country, a boss is fought at the end of every world. Some bosses are a larger version of a normal enemy. Every boss level has a unique, a change from Donkey Kong Country where every boss stage takes place between piles of banana bunches. Every boss's name in the game begins with 'K'.

Items and objects
A variety of items and objects appear throughout the levels, and they each have a unique purpose.

Barrels
Barrels are prominent objects throughout the Donkey Kong series. Multiple variants of these objects exist, many which are featured in Donkey Kong Country 2.

Collectibles
There are a few unique items that are collectibles, which the Kongs are required to collect in order to complete the game. They appear in most levels.

Supporting locations
There are five unique locations which are hosted by a supporting character, and these areas appear in most worlds.

Cheats
In the original version, when the player starts a new file, they can press Down numerous times to navigate down to the hidden Cheat Mode option. While highlighting the option, the player can press a combination of buttons to enter one of two cheats:


 * One cheat removes all the DK Barrels. It is activated by entering: B, A, Right, Right, A, Left, A, X
 * One cheat causes the Kongs to start with 50 lives. It is activated by entering: Y, A, Select, A, Down, Left, A, Down

The Game Boy Advance version has its own Cheats menu (under Options), where the player instead inputs a cheat from a keypad of capital letters. There are nine cheats that they can enter.

Alternate versions
In addition to regional differences, there are two main revisions of the SNES release. Changes from the first version:


 * V1.1
 * Jungle Jinx and Klobber Karnage both have their bonus areas' color schemes swapped from the previous version.
 * King Zing moves faster during King Zing Sting.
 * Infinite throwing jump glitch fixed.
 * Various bugs fixed.

Differences in the Game Boy Advance version
As was the case with the Game Boy Advance remake of the original Donkey Kong Country (and the later remake of Donkey Kong Country 3), changes have been made to the game, including:
 * An intro cutscene is played when the player starts a new file, which is an abridged version of the story from the manual. There are some differences, most of it being dialogue:
 * Funky Kong starts off surfing the waves but accidentally falls into the water.
 * After Cranky talks with Donkey Kong, The Flying Krock hovers above Donkey Kong. Kaptain K. Rool orders his minions (a Krook, a Kannon, and a Kaboing are shown) to kidnap Donkey Kong as a means to ensure that Donkey Kong does not interfere with his plans. Two ropes drop beneath the airship, and eight Klingers (four on each rope) slide down into the trees. Two green Kutlasses ambush Donkey Kong on each side and tie him up. Donkey Kong is pulled up into the airship, where K. Rool tells Donkey Kong that he will never be seeing his friends or DK Island again.
 * Diddy and Dixie ask Cranky to read the note aloud. The note is nearly identical to the one in the manual except that the salutation was removed, "To the yellow-bellied, land-lubbing Kong Family:".
 * The manual story describes Diddy and Dixie arguing with Cranky over them rescuing Donkey Kong. It also describes Funky and Wrinkly originally not wanting to help rescue Donkey Kong. This does not happen during the cutscene.
 * At the end of the cutscene, Funky suggests that all of them go tomorrow before rescuing Donkey Kong. Diddy insists on leaving immediately, and says that Enguarde will take them.
 * The last level in K. Rool's Keep, Stronghold Showdown, in the original, was a small room where Donkey Kong was found tied up and suspended, and Diddy or Dixie would do their victory dances, only to see DK get snatched away. In the Game Boy Advance version, the level is on the castle roof, and the player must fight a new boss, Kerozene.
 * Kudgel's pants change from yellow to red.
 * The game's graphics are slightly brighter because original Game Boy Advance units do not have a backlit screen. This removed the dark atmosphere of the original version.
 * This makes the Lost World look much less menacing though, and Glimmer the Angler Fish has changed from practically mandatory to just helpful due to the increased lighting in Glimmer's Galleon.
 * The background of Cranky's Video Game Heroes was changed to have a beach theme.
 * This also gets rid of the night carnival theme the original Krazy Kremland had, in favor for a sunset one. This is also reflected in the two Roller Coaster levels, Target Terror and Rickety Race, which show a sunset in the scenery.
 * The file selection screen at the beginning now has Diddy Kong as a cursor, a la Donkey Kong Land 2. Additionally, in the British English, French, German, Italian and Spanish versions, the title screen itself is the box art of Donkey Kong Land 2 (the American English release has a title screen based on the box art from the original Donkey Kong Country 2, while in Japanese it is based on [[Media:Swamp DKC2 group art (alt).jpg|promotional artwork]] of Diddy and Dixie exploring a swamp area).
 * Cranky Kong talks to the Kongs after they have defeated a boss, which also occurs in the Game Boy Advance versions of Donkey Kong Country and Donkey Kong Country 3.
 * Swanky's quiz is redesigned in the remake and has some new questions. Candy Kong also appears as his assistant.
 * The view from the windows in Kong Kollege is different based on the world's setting.
 * The incorrect math equations on the board were changed, and the heading was changed to read "Sums".
 * A new game mode called Diddy's Dash is available from the start. In this mode, the player can only play as Diddy and must get to the end of the level as fast as possible. There are no Star Barrels; instead, multiple checkpoints are scattered throughout the stage. If Diddy gets hit by an enemy or obstacle, he instantly appears back at the last checkpoint.
 * Minigames have been added to the remake, including Bag a Bug, Expresso Racing, and Funky's Flights. Tiny Kong appears in some of these.
 * Funky's Biplane Barrel is replaced with the Gyrocopter, which the Kongs can travel around the world map with for free, after they have completed Aerial Loop.
 * The Monkey Museum has been replaced by Cranky's Hut.
 * There are more color variations for Kaboings and Flotsams than the original.
 * When the Kongs defeat Krow, his spirit, Kreepy Krow, comes out of his corpse and flies away.
 * The boss level Kleever's Kiln has lightning effects in the background scenery.
 * Instead of just a title screen and file select, a new main menu was added with three options: Start (which represents the file select), Diddy's Dash, and Bonus Games.
 * Unlike the original game, all the levels that the player unlocks for the Lost World are accessible from any entrance to it.
 * In Cranky's Video Game Heroes, Link and Yoshi were switched to second and third place each. The "No Hopers" trash can, Sonic's shoes, and Earthworm Jim's ray gun were also removed.
 * 28 more Cranky's Video Game Hero Coins were added, bringing the total number to 68.
 * The Super Nintendo controller does not appear in K. Rool Duel.
 * The song "Disco Train", which plays on Roller Coaster levels, has been altered to remove the screeching sounds during its intermission.
 * Nearly all sound effects were changed, including the Kongs, enemies, bosses, and even effects such as explosions and wind. Some enemy voices were taken from Donkey Kong 64 and Diddy Kong Racing.
 * Dixie's sound effects were reused from Tiny Kong in Donkey Kong 64.
 * The hidden music test provides titles from the Official Soundtrack instead of identifiers over the level scenery. However, "Stickerbush Symphony" was renamed to "Stickerbrush Symphony."
 * Wrinkly Kong gives a scrapbook to Diddy and Dixie as their "homework". Wrinkly asks them to fill every page with the photographs that they find.
 * A new menu was added to the world map, allowing the player to save their game at anytime, review Wrinkly's and Cranky's hints, use the Gyrocopter, check the scrapbook, and check minigame high-scores.
 * Swanky Kong charges ten Banana Bunch Coins for rematches against a boss. After Diddy and Dixie defeat the boss, Swanky rewards Blue Balloons to them.
 * In the original, when Dixie does her Helicopter Spin, Diddy would float behind her, motionless. In the remake, he somersaults behind her.
 * The death and end-of-level music no longer changes depending on the level. It instead changes depending on which character is being used at the time.
 * The music "Run! Rambi, Run!" that plays when King Zing chases the Kongs in the original version of Rambi Rumble was replaced by the music heard when racing against Screech in the remake. Despite this, the original music can still be heard in the Sound Test.
 * The world maps were redesigned to be larger and more zoomed in.
 * Additionally, Donkey Kong Island is no longer shown from the Gangplank Galleon and K. Rool's Keep world maps.
 * A cheat that allows the player to obtain all Kremkoins in the first level is no longer present. However, it can still be done by entering the code, "FREEDOM" in the password screen.
 * The player's lives and Banana Coins are now saved, instead of losing them whenever the game is turned off after saving.
 * When Kaptain K. Rool is defeated, Donkey Kong knocks him from the Flying Krock via the cockpit, rather than shooting him through the roof. Another scene shows The Flying Krock about to crash, with Funky Kong bringing the Gyrocopter to evacuate Donkey Kong, Diddy, Dixie, and Cranky Kong from the ship just before it gets destroyed. Also, during K. Rool's fall, he is no longer eaten up by sharks after falling into the waters around Krem Quay.
 * The Krocodile Kore ending was also changed a bit. From a distance, Donkey Kong, Diddy, and Dixie witness Crocodile Isle sink underwater. Celebratory music was added in the background, and K. Rool says that he is not through with the Kongs and that he cannot be stopped. His escape is prevented by Funky Kong, who drops bombs from the Gyrocopter onto K. Rool, who remains adamant on getting revenge on the Kongs.
 * Kaptain K. Rool now utters grunts just before his blunderbuss forcibly expels a cannonball. Originally, he only makes sounds when knocked unconscious after each phase of the final battle (which were reused from Krusha).

Quotes

 * Wrinkly Kong
 * "All those Kremlings want to do is learn how to fight and squash monkeys!"
 * "Those naughty crocodiles! All they want to learn is how to fight and squash monkeys, Tsk!"
 * "When you see Kaptain K. Rool, can you ask him if he has done his homework?"
 * "Hurry along! School is nearly finished! You need to study a little more if you're going to beat the Kremlings!"
 * "You're looking a little weary dear. Would you like to save your game?"
 * "Good luck, children."
 * "Be careful now, Kongs."
 * "Have you been to see my husband Cranky? He complains a little, but he does know everything about this island."
 * "Goodbye, dearies."
 * "Don't be a stranger now."
 * "Well! Just look at all those sums those Kremlings have done. Disgraceful!"
 * "I hope you're better behaved than those reptiles. Why I even caught one sharpening his sword in class yesterday."

Castle Crush glitch
Note: This glitch only works in the SNES and Wii U versions. It was fixed for the Game Boy Advance and Wii Virtual Console versions.

The Castle Crush glitch has become infamous among fans as the series' most fatal glitch. To do it, the player must enter Castle Crush with Diddy Kong as the lead character (Dixie is optional but cannot be the lead character). Then, the player must pick up the first DK Barrel and hold it against a wall. The player must now drop the barrel and quickly pick it up again; if done correctly, the barrel will break but Diddy will act as if he's still holding it. Upon throwing the "invisible barrel", it will be replaced with a nearby object, with the exact object depending on how much of the level had been traversed before throwing. Throughout most of the level, this will cause an enemy to warp in front of Diddy, following which the enemy will often die immediately. If thrown near the top, it will be replaced with the "No Rambi" sign. Both of these outcomes are relatively harmless. However, if thrown shortly after being "picked up," the invisible barrel will be replaced with the nearby Rambi Barrel. The transformation aspect of the Rambi Barrel becomes broken after this happens, and will typically cause Diddy to either turn into a screen-sized glitchy mess, an incorrectly-colored Klubba with no hammer, which stands in place, or a fully-black Kleever, which moves slowly to the side while spinning. In all three of these cases, the game typically will softlock shortly thereafter.

The aftermath of the glitch can vary. Though some have been lucky to escape with no ill effects, others have reported save data being erased due to file corruption, the game becoming corrupted to the point of being near unplayable. Even worse, but rarely, some SNES consoles were damaged and became non-functional because of this glitch.

References to other games

 * Donkey Kong - Cranky makes a direct reference to this game in the intro by saying, "Whisking off maidens and chucking barrels seven days a week, I was!"
 * Donkey Kong Jr. - The overall game's plot was similar to that of Donkey Kong Jr., where Donkey Kong was abducted by an old foe (Mario in the case of Donkey Kong Jr., and K. Rool in Donkey Kong Country 2), with the main protagonist (the eponymous character in Jr., Diddy and Dixie in Donkey Kong Country 2) having to travel from their home to the main villain's home to save Donkey Kong.
 * Donkey Kong Country - Some graphics, notably for Diddy Kong and several items and objects, are reused from this game. The reason the Kongs do not swap the banana hoard for Donkey Kong is because they had just tried hard to get them back in this game. Also a stuffed Winky is found in the game. Additionally, Cranky states that Donkey Kong Country 2 will never be as good as Donkey Kong Country, and then says that it was "rubbish". The sound effect Steel Barrels play can be heard in Kannon's Klaim, and when Kleever is hit by a cannonball. Steel Kegs cameo in the "ship hold" level type's scenery.
 * Donkey Kong Country 2: Diddy's Kong Quest - The remake references the original, as when the monkeys defeat Kerozene Cranky says "I bet you didn't expect that!", as Kerozene did not appear in the original; also K. Rool says "You didn't think it would be so easy did you?" as Kerozene appears.
 * Mainstream Mario - Mario makes an appearance as a video game hero as first place or second place depending on Cranky's Video Game Hero Coins obtained.
 * Yoshi - Yoshi appears as a video game hero in second or third place in the SNES Version and third place or ranked out in the GBA Version depending on Cranky's Video Game Hero Coins.
 * Super Mario Bros. - The instruction manual's description of the Minus Barrel jokingly states that it will send the player to the Minus World.
 * The Legend of Zelda series - At Cranky's Video Game Heroes, Link can be seen in third place.
 * Earthworm Jim series - Earthworm Jim's discarded blaster is seen among the "No Hopers" pile in the original SNES game.
 * Sonic the Hedgehog series - Sonic's discarded shoes is seen among the "No Hopers" pile in the original SNES game.

References in later games

 * Donkey Kong Country 3: Dixie Kong's Double Trouble! - Wrinkly mentions how she had given up working in a school, which was her occupation during Donkey Kong Country 2. Also, many of the item sound effects and graphics in Donkey Kong Country 2 are used again in this game. In the Game Boy Advance version, Swanky looks the same as he did in Donkey Kong Country 2.
 * Donkey Kong Land 2 - A direct semi-sequel to Donkey Kong Country 2, in which most of the level names and bosses remained the same.
 * Donkey Kong 64 - Banana Coins, which debuted in Donkey Kong Country 2, make a return. Paintings of Kaptain K. Rool hang in sunken ships in this game. In the Game Boy Advance version of Donkey Kong Country 2, in Funky's Minigames "Kongnapped" and "Kongnapped 2", Tiny Kong appears.
 * DK: Jungle Climber - Funky's Theme in this game is a cover of the theme Funky the Main Monkey.
 * WarioWare: D.I.Y. Showcase - The microgame DK Country is based on the game.
 * Donkey Kong Country Returns - Ship levels and volcanic levels make a return as well as Banana Coins.
 * Donkey Kong Country: Tropical Freeze - The enemies in this game are vikings known as Snomads, but since vikings are a type of pirate, that could be a reference to Donkey Kong Country 2. Also, Dixie Kong returns as a playable character, and her gumball gun and air guitar idle animation (as well as playing a real guitar during the ending) are reminiscent of her blowing bubble gum idle animation and victory animation, respectively, from Donkey Kong Country 2. A bramble level returns, and is named Bramble Scramble after the one in Donkey Kong Country 2.
 * Super Smash Bros. Ultimate - In this game, one of King K. Rool's attacks involves him using his blunderbuss and he also wears his pirate hat when using the move. Kaptain K. Rool also appears as a Spirit in this game, using his artwork from Donkey Kong Country 2: Diddy's Kong Quest. In King K. Rool's announce trailer "The Rivals", Donkey Kong and Diddy Kong when witnessing King K. Rool knock away King Dedede (who had posed as the Kremlin leader as a prank) had their eyes comically bulge out far enough to shatter part of the windows of the treehouse in horror, referencing Diddy and Dixie Kong's reactions when about to face a boss in this game (and to a lesser extent, Donkey Kong's reaction whenever Kaptain K. Rool regains consciousness and starts the next phase of the final boss battle).

Rare Witch Project preview and German strategy guide
The Rare Witch Project website once had previews of several upcoming enemies and characters for Donkey Kong Country 2: Diddy's Kong Quest. Among these enemies was a sinister looking character simply dubbed "Mr. X". Mr. X was an early version of the enemy Kackle, a ghostly Kremling that appears in the level Haunted Hall and chases the Kongs throughout the level in the final version of the game. Mr. X was a phantasmagoric white Kremling with red eyes, wearing a large black jacket covered in army medals, he also possessed two small hooks for hands. Despite his status as an unused element, Mr. X somehow managed to be included in the official German player's guide, which cryptically states that he is a character no one has known or has seen.
