The Underchomp.

The Underchomp include three Chain Chomps that have to be fought in order to get past the third Doorguy. The first one is the Red Underchomp, the Blue Underchomp, and the Yellow Underchomp. Piccolo can be used to easy defeat the Underchomp. The fight against the Underchomp is resembles a traditional RPG battle, whereas the rest of the game is more of a sidescroller.
