Underchomp

The Underchomp is a red, yellow, and blue 3-headed Chain Chomp, that acts as a guard dog of The Underwhere in Super Paper Mario. It is located in Underwhere Road. Beating the Underchomp is Dorguy the Third's test.

Mario, Luigi and Bowser face against this beast in a far different way from other enemies in the game; they fight the creature in a turn-based battle, though not in the same fashion as other Paper Mario games. The fashion of this battle is comparable to classic Dragon Quest, Earthbound or Final Fantasy battles, as there are many options to choose from.

Each head has a special ability. The Red Underchomp can breathe crimson fire, the Blue Underchomp can breath very hot blue fire, and the Yellow Underchomp has stinky breath. Underchomp can also charge up for one turn and attack stronger later.

Battle Strategy
Using Bowser and Thudley to attack the Underchomp is the most effective way to defeat the massive enemy. If the heroes found Piccolo the Pixl, then it will make the battle that much easier. By using Piccolo's power, the heroes can make the Underchomp fall asleep for several turns. Boomer is a great choice for damaging and defeating the Underchomp.
