From the Super Mario Wiki
“I'm totally starving! Seriously. I mean, just look at me! I'm down to bones over here!”
Dry Bones (also known as Skeleton Koopas) are skeletal versions of Koopa Troopas mainly found in towers and castles. These undead Koopas often collapse when attacked, but they soon revive themselves and become normal once again. Dry Bones first appeared in Super Mario Bros. 3, in which they are an edit of a Koopa. They have since become a staple in Mario spin-off games. Dry Bones is ordinarily a lightweight character in games and is often accompanied by Boo. The Dry Bones emblem is a side-view of their heads.
 Super Mario series
 Super Mario Bros. 3
Dry Bones' debut is in the game Super Mario Bros. 3. In it, Bowser raids the Mushroom Kingdom with his Airships, kidnaps Princess Toadstool, and transforms all of the Mushroom Kings into creatures in the process. Dry Bones can be stomped on the head and turned into a pile of bones; however, they soon regenerate. Unlike normal Koopas, Dry Bones is immune to the tail of Raccoon Mario and the fireballs of Fire Mario but can be defeated with a Star or, if the player has access to one, a Hammer Suit. Dry Bones appear most prominently in the multiple Fortresses of the game, where they often accompany Boos and Thwomps. The first level that they appear in is the Fort of World 1.
In the remake Super Mario Advance 4: Super Mario Bros. 3, Dry Bones can be defeated by the Cape Feather. This item, originally from Super Mario World, can only be obtained by scanning the "Cape" card with the e-Reader.
 Super Mario World
Dry Bones reappear in Dinosaur Land when Bowser takes Princess Toadstool hostage while on vacation in the game Super Mario World. Dry Bones retain their ability to rebuild itself when stomped from Super Mario Bros. 3. This time, however, they can be permanently defeated with the cape or with the star power-up. They can be eliminated even when they are crumbled with a swing of the cape. The Dry Bones of Dinosaur Land appear somewhat different from the Super Mario Bros. 3 versions of them, as they are much taller, being about as tall as Mario, and they have longer necks. Some of the Dry Bones in this game can throw bones at Mario. Super Mario World is the first game that featured this variation of bone-throwing Dry Bones. In the game, Dry Bones can solely be found in the various Fortresses and Castles around the map. Once again, fireballs have no effect. This is the first platformer where they turn around at ledges instead of just falling upon reaching one similar to Red Koopas.
 New Super Mario Bros.
Dry Bones are common in the various Towers and Castles of New Super Mario Bros.. Much like previous platformers, when Dry Bones are jumped on, they crumble; in New Super Mario Bros., their head detaches and bounces away. Once they collapse, the Dry Bones soon revitalize themselves by reattaching their heads. If the head falls into a pit or lava, it takes longer for it to reanimate itself.
A new subspecies is also in the game: Super Dry Bones. This species is essentially a giant version of a normal Dry Bones. Similarly to their smaller cousins, they can only be found in various castles and fortresses. It takes a Ground Pound to crumble them, and they rejuvenate themselves just as quickly as a normal Dry Bones. Both types of Dry Bones can be permanently defeated by a Mega Mushroom, a Star or a Blue Shell. The Super Dry Bones cannot be hurt at all by Mini Mario. Their immunity to fire remains constant in the game. Also, Dry Bowser, a Dry Bones version of Bowser, makes his debut in this game.
 Super Mario Galaxy
Dry Bones also appear in Super Mario Galaxy, when Bowser once again kidnaps the princess and tries to take over the universe. Dry Bones only appear in the Dusty Dune Galaxy, Bowser's Dark Matter Plant and the final level, Bowser's Galaxy Reactor. Unlike normal Koopas, they are bipedal, but appear as a quadruped. They are able to regenerate themselves, just as they did in previous games. When a Dry Bones successfully attacks Mario or Luigi, it cackles similarly to a Boo. The only way to defeat these Dry Bones is by touching them while using a Rainbow Star, destroying them with a Bullet Bill, or luring them into quicksand. They give three Star Bits when defeated. If they are jumped on, spun or attacked with a Green Shell, they crumble, but revive after a few seconds, very much as in the previous Mario platformer games. They are more aggressive than in other appearances, and will chase the Mario Bros. once they've seen them. Unlike in their previous appearances, Dry Bones can fall off the ledge.
 New Super Mario Bros. Wii
Dry Bones reappear in New Super Mario Bros. Wii. They are commonly found in tower and castle levels. They act the same way they did in the game's predecessor. However, there are new means of defeating a Dry Bones; players need to use a Star, a POW Block, a Koopa Shell, or the Ice Flower/Penguin Suit to defeat a Dry Bones. In the original New Super Mario Bros., once they reattach their heads and fully regenerate, the player can jump on it to make it collapse again. However, in the Wii version, the player can make the Dry Bones collapse again, while its rejuvenating to stand up.
 Super Mario Galaxy 2
Dry Bones reappear in the game's sequel, Super Mario Galaxy 2 again, on two legs in a hunched position. They feature the same aggressive behavior and resistance to most attacks that was featured in the original. They appear in Bowser Jr.'s Fiery Flotilla, Bowser's Lava Lair, Bowser's Gravity Gauntlet, Bowser Jr.'s Boom Bunker, Bowser's Galaxy Generator and the Slipsand Galaxy.
 Super Mario 3D Land
Dry Bones appear in Super Mario 3D Land. They act the same way as they do in the Super Mario Galaxy games. They are hunched over and when they see Mario they will charge at him attempting to cause damage. When attacked they will collapse and then soon reconstruct like in most games they appear in. Their eyes turn red for a second when they regenerate. They appear alongside many Draglets and Thwomps in most of the castles in the game.
 New Super Mario Bros. 2
Dry Bones and their mega counterpart appear once more in New Super Mario Bros. 2. Like its predecessors, they are found in towers and castle levels. However, they are also be found in non-boss levels, such as in World 6-A. They have a similar appearance as in New Super Mario Bros. Wii and can be defeated with a Star or Gold Flower.
 New Super Mario Bros. U
Dry Bones reappears in New Super Mario Bros. U behaving in the same way as in previous games, Super Dry Bones also reappears, the Bony Beetle of Super Mario World is also in the game. Also once the Dry Bone reconstruct, the eyes flash a red glare, similar to the Dry Bones eyes in "Super Mario 3D Land".
 The Adventures of Super Mario Bros. 3
Dry Bones make a few appearances in The Adventures of Super Mario Bros. 3.
 Mind Your Mummy Mommy, Mario
 Never Koop a Koopa
 Do the Koopa
They have a role in the episode "Do the Koopa", in which one tells King Koopa that upon spotting them, Mario, Luigi, Toad and Princess Toadstool have snuck into Dark Land and are attempting to find the Doom Dancer Music Box. Later on, Mario's group encounters more Dry Bones that they crush with the debris of broken Brick Blocks. They are later uncovered and freed by Cheatsy Koopa, Bully Koopa, and Big Mouth Koopa.
 Recycled Koopa
 Super Mario World television series
Dry Bones also appear in the Super Mario World animated series, in the episode "Send in the Clown" and "The Night Before Cave Christmas". Here, both of them makes a very small appearance as they try to keep Mario and Yoshi from infiltrating Bowser's Castle or stop Mario from getting a feather. The Dry Bone grabs a bone from out of its throat and throws it at Mario.
 Nintendo Comics System
A single Dry Bones appears in the Nintendo Comics System in the story It's Always Fair Weather as the pilot of Bowser's personal helicopter. When Bowser expresses outrage after discovering his image is being used for a carnival dunking booth, the Dry Bones cheerfully responds to his complaint of "I am really insulted!" with "Gee, I'd be flattered!" The two try to ruin the fair with miniature tornadoes created by the helicopter, but are stopped by Mario, who uses the copter against Bowser, launching him into the dunking booth with it.
 Nintendo Adventure Books
In Koopa Capers, Luigi can find a pit filled Dry Bones in Bowser's Fortress, and will fight several of them if he decides to try and reach a door at the bottom of the hole; the powdered toes of a Dry Bones are also one of the ingredients needed by Wendy O. Koopa for a magic potion she is brewing.
In Flown the Koopa, if Mario thwarts Magikoopa's attempt to freeze him and his brother, the angered magician will throw out some bones, and use his magic to animate them as two Dry Bones. Depending on how the accompanying puzzle is solved by the reader, the Mario Bros. will either trick the Dry Bones into charging into a broom closet and lock the door behind them, or they will try to smash the skeletons with their plungers, only to have this backfire on them when the Dry Bones regenerate, combine, and knock them both out.
 Hotel Mario
Dry Bones (known as Skeleton Koopas in the game) appear as enemies in the CD-i game Hotel Mario, when Bowser and the Koopalings once again kidnap Princess Toadstool. Skeleton Koopas only appear in the level Ludwig's Thump Castle Hotel. As usual, the Skeleton Koopas in this game revive themselves once they are knocked out. They, however, can be defeated with a Fire Flower, which is impossible in games before this one. This weakness to fire reappears in the Paper Mario series of games.
 Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Dry Bones appear as enemies in the Sunken Ship. They guard the ship's midsection. The skeletal Koopas have an infinite amount of HP, meaning that regular Attacks will never defeat them. The only way to defeat them is with a special attack, which defeats them instantly. When defeated, they simply crumble on the overworld map. However, they always resurrect after a short amount of time and attempt to re-engage battle with Mario. A stronger sub-species of Dry Bones known as Vomer makes an appearance in Barrel Volcano.
 Paper Mario
Dry Bones reappear in Paper Mario in Bowser's Castle when Bowser captures Princess Peach and her castle. Dry Bones only appear in Bowser's Castle in the game, protecting the upper regions of the castle from Mario and his partners. They are a relatively powerful enemy, as they appear about halfway through the Castle. This variation of Dry Bones is able to walk upright and throw bones at Mario. They are also capable of building more of themselves, with the same amount of HP as the original unit. They regenerate themselves if all their HP is taken, but can be permanently defeated with flames or explosions, which they are immune to in previous games.
 Paper Mario: The Thousand-Year Door
There are four different varieties of Dry Bones in Paper Mario: The Thousand-Year Door during the invasion of the X-Nauts. The first type appears in Hooktail Castle. This variety is named Dull Bones and is the weakest in the game. This type of Dry Bones cannot come back to life once its HP is taken, but it is able to build more allies. Many dead Koopa Troopas appear all around Hooktail's Castle, many of which are previous residents of Petalburg. Some of these are animate Dull Bones and others, like Kolorado's Father, are truly dead.
Also in the castle is a different variety of Dry Bones, appropriately named Red Bones. This alteration is slightly more powerful than the Dull Bones and has a red tint to its entire body. In the first battle, Red Bones is accompanied by four Dull Bones. This variety can also create reinforcements of more Dull Bones and can revive itself if fallen, unlike its weaker counterparts. Red Bones is first encountered by Mario and his party in Hooktail's Castle, and it later reappears in the Palace of Shadows. In the first confrontation, Red Bones calls upon countless numbers of Dull Bones and they swarm in on Mario and his partner. The player has to use Mario's hammer to scatter the Dull Bones and engage the Red Bones in a battle, or get tossed out of the castle.
Later in the game, normal Dry Bones appear in the Palace of Shadows and the Pit of 100 Trials. The normal variation is able to get back up once defeated, and is also able to build more allies at any point in a battle. To damage Mario and his partner, Dry Bones can throw bones at the pair. The normal Dry Bones is stronger than both Red Bones and Dull Bones. They will again collapse if beaten and get revitalized when the battle isn't finished quick enough. Fire attacks (such as Fire Drive, Fire Flower and Fiery Jinx) will beat them forever, just like in the original Paper Mario.
The palace is also home to Dark Bones. This variety is to Dry Bones as Red Bones is to Dull Bones; Dark Bones, much like Red Bones, are stronger than and able to build their weaker counterparts. Dark Bones are fought twice in the palace. The first encounter is when the Dark Bones call in innumerable amounts of Dry Bones, much like Red Bones do in Hooktail's Castle. The player once again has to use his hammer to clear away the minions and get to the leader of the troop, initiating a fight. If the player does nothing while Dry Bones are crowding around them, he or she gets a Game Over.
All of the types of Dry Bones are encountered once more during Mario's travels. They are encountered all at once in one room of the Palace of Shadows. The four types have to be defeated in the order of weakest to strongest: Dull Bones, Red Bones, Dry Bones, and finally Dark Bones. Doing so gives Mario a key to another part of the palace.
Dull Bones also occasionally appear in the Audience. Dull Bones are the only audience members that don't give out Star Power upon successful Action Commands and Stylish Moves; they do, however, give out Star Power for Appealing.
 Super Paper Mario
Super Paper Mario once again features Dry Bones. When stomped, Dry Bones collapse, but come back very quickly, much like previous platformer games. Like in previous Paper Mario games, it throws bones at Mario and company. Dry Bones are found in The Underwhere and the Flipside Pit of 100 Trials in this game.
A new subspecies – the Dark Dull Bones – appear in the Flopside Pit of 100 Trials, where all the enemies are dark counterparts of the regular ones. This subspecies is stronger than its colored cousin, like all Dark enemies are.
 Paper Mario: Sticker Star
Dry Bones appear in Paper Mario: Sticker Star, but their appearance is closer to their current main series' appearance, unlike the Dry Bones of previous Paper Mario games, whose appearance was based on the species' artwork for Super Mario World. They are found in World 2. Dry Bones also appear during the boss fight against Petey Piranha in Rumble Volcano, where Petey Piranha can spit them out to battle Mario. A Dry Bones can either attack by throwing a bone or by folding itself into a bone and tossing itself at Mario. If Mario defeats a Dry Bones in battle, it will turn into a pile of bones in the overworld, but will revive itself shortly after. Defeating a Dry Bones occasionally gives Mario a Bone sticker.
 Mario & Luigi: Superstar Saga
Dry Bones reappear once more in Mario & Luigi: Superstar Saga in the Beanbean Kingdom when Princess Peach's voice is stolen. The Dry Bones of this game look somewhat different from other versions, as they have no shell. They do walk on four legs just as the ones in Super Mario Bros. 3. They are found all along Hoohoo Mountain as the Mario Bros. try to scale the peak. Dry Bones attack by launching their heads at their opponents. If a Dry Bones' head twists counterclockwise, it attacks Mario; if its head spins clockwise, then Luigi is the victim. To counterattack the Dry Bones while the creature is attacking, the Mario Bros. have to jump onto the spinning bone head as it flies towards either one. The Bros. can also initiate a battle with an attack if one of the pair stomps on the Dry Bones' body or its head. When they are defeated, Mario and Luigi would occasionally receive a Mushroom.
 Mario & Luigi: Partners in Time
Dry Bones appears as an enemy in Mario & Luigi: Partners in Time. Dry Bones reside in Yoob's Belly. When a battle is initiated, a Dry Bones throws bones at Mario and Luigi. Usually, the Dry Bones stays still while throwing the bone, which causes the bone to go towards a single brother. A Mario brother must jump to dodge this attack. If the Dry Bones jumps before throwing a bone, however, the bone bounces over the brothers' head and causes damage if one of the Bros. jumps into the bone. Furthermore, Dry Bones is able to attack the Bros. one after the other. If the Dry Bones clacks, it attacks Mario before attacking Luigi, and if the Dry Bones twirls its head, it attacks Luigi before attacking Mario.
Later in the game, large Dry Bones statues appear in Gritzy Desert. When these are encountered, the player has to split the babies and the adults. After doing this, they have to hit four blocks within ten seconds of each other. There are two pairs of blocks in the desert, and once the two pairs are hit, a hidden door to the Koopaseum opens.
 Mario & Luigi: Bowser's Inside Story
In the game, Mario & Luigi: Bowser's Inside Story, some Dry Bones are seen in the Fawful Theater. One is in the lobby of the building, and the rest attend Fawful's show. There are also two Dry Bones standing in the watchtowers of Bowser's mechanized castle during Bowser's fight against it.
 Mario Baseball series
Mario Superstar Baseball is Dry Bones' spin-off debut. Dry Bones is introduced as a technique character as a part of Bowser's team. His four colors are white (by default), red, green, and blue. His strongest points are pitching and fielding. He is an average runner and below average hitter. This is one of Dry Bones' only appearances as playable from the start. Dry Bones Buddies in the game are Koopa Troopa and Bowser.
Dry Bones also appear in the sequel Mario Super Sluggers. Dry Bones is a powerful hitter in this game despite being a rather weak batter in Mario Superstar Baseball. Like in Super Mario Galaxy, the Dry Bones in this game have two voice sets: one similar to the previous title's, and an older Boo-like voice from Super Mario 64. Each Dry Bones has good chemistry with a Koopa Troopa and Bowser. Oddly, its chemistry with Boo is neutral, despite having some similarities with that species. Dry Bones is the only team player with alternate colours who pitches with its left hand.
 Super Princess Peach
Dry Bones later appear when Bowser steals the Vibe Scepter and kidnaps the Toads along with Mario and Luigi in the game Super Princess Peach. They only appear in Shriek Mansion and Bowser's Villa. These Dry Bones look similar to the models used in future games. They are able to throw bones at Princess Peach, and the bones can be blocked by a swipe from Perry. If a Dry Bones itself is hit or jumped on, it crumbles and revives itself in about three seconds, which is relatively fast compared to previous games. Dry Bones can be defeated permanently when Peach attacks them with her Rage vibe. This weakness is a throwback to Paper Mario, in which Dry Bones are weak to fire. There is also a subspecies that is introduced in the game. This variation is called the Sad Dry Bones, and it weeps openly whenever it is seen. It is also able to throw bones at the Princess, except that these bones are much faster and more difficult to avoid.
 Mario Party series
Dry Bones appears in four titles of the Mario Party series. The first game it appears in is Mario Party 7 as an unlockable, playable character. It can be purchased in the Duty-Free Shop for a price of 1000 Cruise Mileage Points. The Magic Orb is Dry Bones' special Orb which doubles the number on the dice block and then turns Dry Bones invisible. In artwork of the game, Dry Bones is usually partnered with Boo.
Dry Bones reappears in the next game in the series, Mario Party 8, once again as a playable character. This time, it is available from the start of the game.
Dry Bones' biggest appearance in the Mario Party series is in Mario Party DS where it appears as a non-playable boss character. In the story mode, it takes over the board DK's Stone Statue and turns Donkey Kong into stone. Diddy Kong asks Mario & co. to rescue Donkey Kong and then the Party begins.
On the board, Dry Bones can be found sleeping in a coffin. If the player stops on a Green Space nearby its coffin, Dry Bones wakes up and lifts the coffin lid slightly. It then shuts the lid with such an amount of force that the player is sent back to the start or right next to the Star. When the player completes the board in story mode, a boss fight with Dry Bones begins in the minigame Hexoskeleton. Dry Bones attempts to destroy the characters by crushing them underfoot and the characters must Ground Pound switches on the battle field to attack it with lightning. It is also possible to acquire a trophy of a defeated Dry Bones by beating the Hexoskeleton minigame five times.
In Mario Party 9, Dry Bones is the mini-boss of Boo's Horror Castle. He is summoned by Bowser to work with King Boo in destroying Mario and his friends. The boss minigame he is faced in is called Deck Dry Bones. In the game, Dry Bones will leap from platform to platform, and the players damage him by picking cards with the same pattern as the platform he is standing on. Dry Bones cards also appear; selecting these will allow Dry Bones to attack the player that does so.
Three Dry Bones also appear in the minigame Ruins Rumble. Despite being non-playable characters, they and the player's opponents must be defeated in order to win the minigame. They also have an appearance in the minigame Smash Compactor, in which they raise the compactor after each round. During the introduction to the minigame, a Dry Bones may also appear on top of the compactor.
 Mario Kart series
 Mario Kart DS
Dry Bones' first appearance in the Mario Kart series was in Mario Kart DS. It is a playable character and unlocked by winning the gold trophy of the Nitro Grand Prix in 50cc. Its karts are the Standard DB, the Banisher, and the Dry Bomber. These karts have the best handling and acceleration stats in the game, but are middling in weight and speed. Dry Bones is the staff data used on Donut Plains 1 and has a time of 1:08:027 in the Dry Bomber. It is also the staff data on Banshee Boardwalk and has a time of 2:14:403 in the Dry Bomber.
 Mario Kart Wii
A Dry Bones reappears in Mario Kart Wii. It is a playable, unlockable character and is unlocked by earning a Gold Trophy in the Leaf Cup in 100cc. It is a lightweight character, which means it has a low top speed but good acceleration and off road ability. Each of its karts are recolored in gray and black. Dry Bones gets a small acceleration and drift bonus, but its best bonus is its mini-turbo. This enables vehicles like the Booster Seat and Bullet Bike to perform slightly stronger mini-turbos after a drift.
 Mario Strikers Charged
Dry Bones makes its appearance in Mario Strikers Charged as a sidekick. Classified as a defensive player, Dry Bones' highlights are its speed and defense, meaning it can react quickly and run fast towards the ball, while its defense is Tackling opponents fiercely to knock them off in a short time. However, like the defensive captains, Dry Bones also shows a bad passing skill and power as to kick the metallic ball immediately on its maximum power.
Its Skillshot is the Shocker. After charging the ball completely, Dry Bones electrifies the ball, making the rival's Goalkeeper or even another competitor unable to move and react briefly for another shot. When evading a potential opponent attack while having the ball, Dry Bones can turn around and disappear, making it almost invincible, capable of passing hazardous obstacles, such as power-ups dropped on the field or dodging the Goalkeeper's moves. However, Dry Bones cannot use its deking capabilities to pass through the electric fence; it will be electrocuted, which results in losing control of the ball. The durability and effect of Dry Bones' deke depends the light the ball is emitting. Therefore, if the light is white, Dry Bones can go further while invisible. Once Dry Bones has performed its evasion in this way, the light of the ball changes back to its lowest power.
 Mario & Sonic series
 Mario and Sonic at the Olympic Games
 Mario and Sonic at the Olympic Winter Games
In the follow-up, Mario & Sonic at the Olympic Winter Games, they appear as rivals. On the Wii, three of them appear along with Dry Bowser as the final rivals in Festival Mode in the event Ice Hockey on the last day. Dry Bowser is the goalie and there are three Dry Bones as the field players. Also in the Wii (Team Festival Mode) and in the DS Version, they appear without Dry Bowser in the event Curling with four Dry Bones instead of three.
 Mario and Sonic at the London 2012 Olympic Games
Dry Bones also appears in Mario & Sonic at the London 2012 Olympic Games. It is the rival of Table Tennis in London Party Mode, and later, Dream Hurdles. When the player defeats it, they'll win a sticker. It's also one of the characters that can be spoken to.
In the 3DS version's story mode, Dry Bones appears alongside Dry Bowser when Toad and Omochao are separated from Mario and Luigi. The two are fearful of them at first, but attempt to stand up to them when Mario and Luigi arrive. Dry Bowser and Dry Bones challenge them to an Olympic event, but the Marios defeat them. The two then escape as Toad and Omochao commend Mario and Luigi for their victory.
