Dorguy the Third

Dorguy the Third is the last of Queen Jaydes's guardian doors in Super Paper Mario. He is found even deeper (than previous doors) in the path from The Underwhere to The Overthere. He must only open to trustworthy people (like the others) and not let any enemies pass by. However, he does not ask questions like his predecessors do. Instead, he summons the Underchomp, a three headed Chain Chomp creature fought in a similar style to EarthBound, and Mario and team must defeat it so Dorguy the Third can grant them access to the next Chapter.

Trivia

 * His face looks exactly like the ones of the Black Chest Demons.
 * His role of forcing the heroes to fight a boss to proceed is reminiscent of the role undertaken by the third Guard Door in Bowser's Castle during the events of Paper Mario, though in that case, the heroes have to fight a boss other than the one the Guard Door intends.
