Haunted Mouse is a color Tom and Jerry short film. It was released to theaters on March 24, 1965.
Jerry the mouse's magician cousin, or uncle, supposedly named Merlin, drops by for a visit, demonstrating his magic by levitating Tom the cat, who was sitting outside Jerry's front door. While preparing dinner, Jerry ends up getting chased by Tom, but Tom ends up grabbing Merlin instead, since both mice are identical. Tom's wicked laughter after grabbing Merlin, whom he thought was Jerry, soon fades, and Merlin hypnotizes the cat, and frees/revives all the creatures that Tom ever ate. Including birds, other mice, and a fish. And he is just getting warmed up, for as soon as he lets Tom out of the hypnosis spell, Tom runs for his nine lives because he thinks the mouse is haunted.
