Billy & Mandy Save Christmas

Billy & Mandy Save Christmas is a one-hour Christmas special based on The Grim Adventures of Billy & Mandy, a series that has aired on Cartoon Network for seven seasons, beginning in 2001.

Synopsis
Santa Claus (Gilbert Gottfried) has been bitten by a vampire — not by the Head Vampire (Malcolm McDowell), but actually by the Head Head Vampire (Carol Kane). Mandy and Grim team up with the Head Vampire, Baron von Ghoulish, while Billy helps Mrs. Claus and the elves around the workshop.

It turns out that Mrs. Claus actually is the Head Head Vampire, who attacks the friends with her army of vampire bat elves. Baron von Ghoulish hides in a Christmas tree as Mandy faces off with Mrs. Claus. Meanwhile, Billy discovers the Vampire Antidote: cookies and milk.

Mrs. Claus is defeated, Santa is restored to life, and Christmas is saved.

On Christmas morning, Grim receives a new scythe, while Mandy only gets coal.
