Mario's Face

Mario's Face is a tech demo for the Nintendo DS. It is an updated version of the Mario face screen from Super Mario 64 that allows the player to move and warp Mario's face with new mechanics than the original Super Mario 64. There is also a Wario face. The Mario head went on to be used in Super Mario 64 DS, though with some aspects removed, and a Wario head replaced with a Yoshi head. The top of the screen also has a screen similar to the updated version of the original Super Mario Bros. in Super Mario All-Stars.

It is possible that the Wario head being added is based off of the Wario Apparition, though this is unconfirmed.
