Chain Chomps have a very simple design. They have a dark blue head, with sharp white teeth and two expressionless eyes. They're attached to a metal chain, which is usually tied to a yellow pole.
Chain Chomps, as stated before, are usually attached to a pole. At certain intervals, they'll jump towards the player, but'll be stopped by its chain. You are able to ground pound this pole, which will free the Chain Chomp. Once freed, it'll jump around in one direction, breaking brick blocks. Once it hits a wall, it'll kill itself and fall down. They can't be hurt by most things.
Chain Chomps appear almost the same as their Wii counterparts, except some things are different. Their heads are now pure black, and their chains are little black balls. Also, their pole is much thicker.
Chain Chomps act the exact same as their Wii counterparts. They'll lash out at the player at specific intervals, but will be held back by their chain. Once you ground pound their pole, they'll bounce off. Though some Chain Chomps are attached to unbreakable walls, so you must dodge them or use the Hammer Suit.
