This is a made-up episode of Fanboy and Chum Chum.
Yo gives Chum Chum her special yo-yo as a tactic into getting him hypnotized into dating her, Chum Chum doesn't know this, so he gives the toy to Fanboy. But, what Fanboy doesn't know is that it isn't just any ordinary yo-yo...it's a "Yo"-yo! He gains an obsession with the toy AND with Yo. Can Yo fix the damage?
