The Grim Adventures of Billy & Mandy
Prank Call of Cthulu
Directed by Sue Perrotto, Eddy Houchins, and Juli MurphyTV-Y7
S5 • E10 Oct 20, 2005When Billy and Irwin start making prank calls, everybody knows that Billy is behind the calls because every telephone has a caller ID. While Billy searches in Grim's trunk in the basement for something to defeat the caller ID, he finds a skull-shaped phone with no caller ID. Grim warns him to not use the phone, because it is used to call the ancient demon Cthulhu, whose sole appearance makes people go mad, and if awakened will cause the destruction of the world. Despite Grim's warning, Billy and Irwin use the phone anyway, and they are sucked into it by tentacles.
