Watch The Grim Adventures of Billy and Mandy online: Episode 2 The Show that Dare Not Speak Its Name

When Grim leaves the house to meet someone he met on the internet, Billy looks inside Grim's trunk for something to entertain himself. Then, Billy finds a magical talking Rubik's Cube, which releases the demon Pinface, who has bowling pins in his head (a parody of Pinhead from Hellraiser). Then, Pinface proceeds to call his minions to conquer Earth, but the minions are more interested in throwing a house party. Later, it is revealed that Grim and Pinface already know each other, and Grim even broke up with Pinface's sister. In the end, Billy's father cheats and solves the magical cube by rearranging the stickers, trapping Pinface and his minions inside it again.
