Four-Headed Bulldog

The Four-Headed Bulldog is a large, light-blue bulldog with four heads that is remarkably strong, each of its mouths having razor-sharp teeth. Only one of this variety is seen in the movie. Its very owner has no strength to contain this beast if it wants to walk in a particular direction. It is defeated when the Beatles and the Lonely Hearts Club Band sing "Hey Bulldog" to get its attention and then run on opposite directions to confuse it.
