PAC-MAN and the Ghostly Adventures

S02:É224 - S02:E224 - Pac's Very Scary Halloween (Pt. 1)

Forever unable to come up with a creature powerful enough to vanquish Pac-Man, Betrayus employs the diabolical Dr. Pacenstein (who is now a scheming brain-in-a-jar) to create a mega monster. The evil brain has plans of his own, however, and transfers his grey matter into Pac's yellow noggin. And of course this all happens on Halloween!
