Billy & the Bully
Tickle Me Mandy
Billy opens a strange book, The Bad Book, that makes him become possessed by the minion of an ancient cosmic entity, Yog-Sothoth, who wishes to open a portal for his master to enter and destroy the planet. Grim and Mandy manage to get Hoss Delgado to exorcise the spirit, but Billy creates an evil portal in the basement where Yog-Sothoth will enter the world. In the end, Yog-Sothoth and The Old Ones kick Billy out of The Dreamlands because they didn't enjoy his presence.

- When Billy gets possessed by Yog's minion, his voice changes so that he sounds just like Zim from Invader Zim. Even his laughter becomes exactly like Zim's. Both characters are voiced by the same person.
