Fanboy and Chum Chum
Yo is another of Fanboy and Chum Chum's classmates. She is a happy-go-lucky girl and loves her Yamaguchi (a parody of Tamagotchi) digital pets, especially a cat named Scampers. She has a crush on Chum Chum, and often wants to play with him like he's a toy. She is shown to be a very talented prankster, dominating Fanboy on Prank Day. Although she can have a villainous side, she is overall very nice. She has black hair styled in pigtails, she  wears a yellow shirt, a plaid skirt, and a frog backpack.
