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. Except this time, he does not ask questions like his predecessors would. Instead, he summons the Underchomp, a three headed Chain Chomp creature fought in a similar style to Earthbound, and Mario & team must defeat it so Dorguy the Third would grant them access to the next Chapter.

Trivia

 * His face looks exactly like the ones of the Black Chest Demons.
