Chain Chomp

Chain Chomps are a recurring enemy in the Mario franchise, in which they first appear in Super Mario Bros. 3. Chain Chomps resemble a ball and chain and are typified by their large, tooth-filled maws and incessant biting. Chain Chomps' behavior is based on that of real-world canines, mainly their barking.

In Adventure Tours mode, a Chain Chomp is found blocking the path in Blizland. Wario is required to get the Chain Chomp to move, in the Blow Away Chain Chomp! mini-game, where he must use his Wario Waft to blow the Chain Chomp off the platform.

Super Smash Bros. for Nintendo 3DS / Wii U
Chain Chomps appear as an Assist Trophy in Super Smash Bros. for Nintendo 3DS / Wii U. They attack by lunging at opponents from their posts and chomping them for multiple hits. If the Chain Chomp falls off the stage, then it leaps back up onto it.

In Super Smash Bros. for Nintendo 3DS, Chain Chomps are also enemies in Smash Run, and attack in the same manner as the Assist Trophy. Their bodies are invulnerable to any attack; the only way to defeat them is by attacking the post until it is free.

Super Smash Bros. Ultimate
A Chain Chomp returns in Super Smash Bros. Ultimate as an Assist Trophy. Additionally, a Chain Chomp appears as an Advanced-class Attack-type primary spirit. It allows no support slots and, when equipped, makes the user slower but more difficult to launch. The corresponding spirit battle involves a metallic Pac-Man and a hostile Chain Chomp Assist Trophy on the Yoshi's Island stage. In addition to the Spirit Board, the Chain Chomp spirit can be obtained from Beedle's Tent for 1,000 Spirit Points.
