Underfist: Halloween Bash (otherwise known as Underfist) is an American animated spin-off special of The Grim Adventures of Billy & Mandy. It originally aired on Cartoon Network on October 12, 2008. The special was going to be the setup for a new series spin-off of Grim & Evil, but Maxwell Atoms's contract with Cartoon Network expired before he moved to Disney Channel for the TV series Fish Hooks, and the special was ultimately the finale of the Grim & Evil franchise.
