Xavier: Renegade Angel Easter Egg - Hidden Pfffr Mascot

Toward the end of the show, when Xavier tears out a sheet of the space time continuum to try and scare away ghosts by pretending to be one, several figures jump out of the gap where the space time sheet was. Most are 3D figures of pictures Xavier drew for his mom as a child (shown earlier in the episode). The last one that jumps out before the screen changes is the PFFFR mascot/logo. (It looks like an apple with a face sitting on a pair of legs with a face.)
