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.

Each head has a special ability. The Red Underchomp can breathe crimson fire, the Blue Underchomp can breathe 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. They are possible to defeat in one turn by using a Shooting Star.

Trivia

 * The Underchomp is based upon the legendary hellhound Cerberus, a giant, three-headed dog who guarded the gates of Hades in Greek mythology. He shares the same weakness; Music.
 * During the battle Mario, Luigi and Bowser can use their special abilities. When Mario uses flip, he dodges the attacks, when Luigi uses spring jump he does a more powerful jump and when Bowser uses fire it simply heats up the metal Chomps, wasting a turn.
 * This battle shares many similarities with the ones from the first game of the MOTHER/EarthBound series : Firt person turn-based battle, black background and same text boxes display. The final boss of MOTHER is also highly responsive to music.
