Boat Mode

Boat Mode is an origami-like transformation in Paper Mario: The Thousand-Year Door. It allows Mario and his partners to traverse across water unscathed, similar to Sushie's overworld ability in Paper Mario; waves will push the boat back, however. Like his other origami-themed forms, the boat form is granted to him in the form of a "curse" from one of the Black Chest Demons in Pirate's Grotto, where it is primarily used. Additionally, there is a minigame in the Pianta Parlor based around this mode.

It is similar to Mario's Plane Mode in that it can only be activated when Mario is on the form's corresponding panel, known as a boat panel (also capitalized). It differs in that Mario is required to touch another boat panel in order to return to normal. Like Boat Mode itself, boat panels function similarly to the wooden docks that Mario uses to mount and dismount Sushie in Paper Mario.
