The Adventures of Timmy the Horse Head
The Adventures of Timmy the Horse Head is an animated children's cartoon. It was released on DVD in 2007, and is a spin-off of The Godfather which tells the story of the life of the disembodied horse head that appears on the old guy's bed in the first Godfather Movie.
In the movie, Timmy the Horse Head is born, and the other horses make fun of him because he is simply a disembodied head with no body. But he teaches them a lesson when he beats them all by winning a horse race (the other horses run while he simply rolls along the ground, with a jockey balanced on top of him).
He then travels to California where he soaks himself in ketchup and lies in an old guy's bed, as a practical joke. It scares the old guy into giving some singer a movie contract.
Then, Timmy befriends a mouse brain and a cow liver, and together they go on a grand adventure through the world. It was praised by critics as "The most emotionally heartwarming film about an internal organ since "beauty and the lower intestine!"
A sequel, in which Timmy goes into space, goes to a zoo, and falls in love with a whale bladder is in the early stages of production. It will be released in 2009.
