Chain Chomps are recurring enemies in the Mario series. They first appeared in Super Mario Bros. 3. These enemies can often be found off the posts holding them down, or sometimes even lack their chains (where they are just called chomps). They resemble a ball and chain. They behave like dogs and even bark. They are a strong and unintelligent species, and are commonly used as guard dogs in most games. One appears in Bob-omb Battlefield and you have break it free to get a star behind a cage.
One appeared in Super Mario 64 and its remake Super Mario 64 DS in Bob-omb Battlefield. In this game, the Chain Chomp acquired its bark for the first time and is used in later games. Mario must ground pound its' post in order for it to break the gate behind it and allow him to retrieve the sixth (seventh in DS version) Power Star.
In Mario & Luigi: Partners in Time, the Pocket Chomp is a Bros. item. At first it appears to be a small Chomp in an orb, but when released it more than triples in size and hunts the brothers across the screen, forcing them to Jump on any enemy in their way. Rarely, a feminine form of a Chain Chomp appears when this item is used. Also, when you battle Elder Princess Shroob, in one of her attacks, she summons her pet, a Shroobifed Chomp, to ram Mario and Luigi.
Chain Chomps are mainly seen with Walker Guys in this game. Chain Chomps are only fought in Neo Bowser Castle and in battle, they mainly attack by charging at either Mario or Luigi. The Chain Chomps also can hurl their Walker Guy masters at one brother and the Chain Chomp will then attack the other brother. When the Walker Guy has been defeated, the Chain Chomp will look around and lose a turn giving Mario and Luigi a chance to defeat it.
In Mario Kart 64, Chain Chomps appear on the Rainbow Road track where they travel at road level in the opposite direction of the racers in a regular zig-zag pattern. If touched, the driver will be sent flying up.
In Mario Kart: Double Dash!!, a Chain Chomp is a usable item for Baby Mario and Baby Luigi, as well as Petey Piranha and King Boo, who have the ability to receive any other character's special item. It pulls the racers forward for a few seconds and bowls over other racers in its path. After a certain amount of time, it abandons the vehicle and goes off on its own. It will follow the course for a few seconds before it goes in a straight line until it runs into a wall or off the course. The Chain Chomp can also be knocked from the owner if the driver gets hit. It is replaced by the Bullet Bill in Mario Kart DS and Mario Kart Wii. Chain Chomps also appear as obstacles on the Mario Circuit and Luigi Circuit tracks, where they will attack the player and make them drag if they get too close. This is a reoccurring concept in later games.
Chain Chomps are wild creatures in the Mario Party series. They were created to resemble a dog on a chain. They, like many other Mario enemies, appear commonly on boards and in mini-games as obstacles.In Mario Party 2, the Chain Chomp appears in a mini-game titled Sneak 'n Snore. Player will try to press a button and get to an opened door without being caught by the Chomp. If the Chomp does catch the player, the player will be thrown into a green pipe and get eliminated from the game.
In Paper Mario, the regular Chain Chomps are only fought alongside Tutankoopa during the boss fight with him in Dry Dry Ruins. Tutankoopa starts to summon Chain Chomps once his HP gets low enough and the Chain Chomps attack mainly by biting Mario. Mario has the choice to defeat them or leave them alone.
In Super Paper Mario, there are Chain Chomps known as the Underchomp are fought as bosses in this game. They are located in Underwhere and are fought as the last trial. There are three types: a yellow, red, and blue one and each have different attacks. Mario, Peach, and Bowser must fight the Underchomp in a RPG style battle using Pixls as weapons. It is recommended using the Bowser/Thudley combo to take down the Underchomp quickly.
In Paper Mario: Sticker Star, Chain Chomps only appear in World 5 in the levels Chomp Ruins and Rumble Volcano. Unlike most Mario games, the Chain Chomps in Paper Mario: Sticker Star cannot be defeated in any way. The only way to get by one is to put it to sleep with any version of the Baahammer then run away from battle. There is a much bigger Chain Chomp at the end of the ruins where Mario must survive for only three turns until it leaves the battle.
