Warp door (Wario: Master of Disguise)

Warp doors are special doors that appear in Wario: Master of Disguise. When Wario transforms into Arty Wario, he can draw a warp door.

In order for it to appear, the player must draw an upright rectangle with a line going through it on the touchscreen. On top of the warp door is a pumpkin-like statue that is shown to be alive. The warp door takes Wario to the hat switch he saved at. If he has not saved, it will return him to the beginning of the episode. If Wario wants to get rid of it, he must wait for it to vanish or draw poop to run into the door and destroy it.
