Door Key (The Underwhere)

The Door Key is an item found in Super Paper Mario. In The Underwhere, Hagra gives Mario a Door Key as a reward for finding her Diet Book. This Door Key is used to open a locked door on Underwhere Road.

In The Overthere, Mario receives yet another Door Key as a reward for rescuing Sunbi from two Skellobits. This Door Key is used to unlock a door at the beginning of the stage. Later in the stage, another Door Key is obtained after freeing Whibbi from a block of ice. This Door Key is used to unlock a door leading to the rest of the level.
