Dorguy
Dorguys are doors found solely in the game Super Paper Mario only appearing in The Underwhere. When first seen, they are normal doors that can't be opened. Using Tippi, when the player points to these doors and presses the "A" button the Door will come to life.
There are only three known Dorguys. The first two will ask questions and the last one will have the heroes battle The Underchomp. The first Dorguy asks questions that seem ridiculously complicated at first, but always end up simple; e.g. "What is my name?". The second Dorguy asks questions involving coloured shapes on a screen a la Brain Age. The third one summons the Underchomp and Mario and co. must fight it in a turn based manner similar to EarthBound. The Dorguys have names: Dorguy the First, Dorguy the Second and Dorguy the Third. Their names are a portmanteau of the words Door and Guy.
