The Invisible Mouse is a 1947 Tom and Jerry cartoon directed by Hanna-Barbera.
While being chased by Tom, Jerry hides in a chemistry set, inadvertently landing in a bottle of invisible ink. After finding his bottom half missing and testing it on his hand, Jerry decides to make himself completely invisible to have a little fun with Tom. At first, the prank works, as Tom begins to think the house is haunted. However, it isn't long before Tom is onto Jerry's scam...
The cartoon provides examples of the following tropes:
- Artistic License – Animal Care: At the end of the cartoon, Jerry drinks a saucer of chocolate milk belonging to Tom and becomes visible again. Chocolate is poisonous to both cats and mice, although tiny amounts of chocolate for mice is okay.
- Cranial Eruption: Jerry's shadow gets a lump when Tom hits him.
- Curb Stomp Cushion: Tom lands one good hit on Jerry by clonking him with a book.
- Failed a Spot Check: There is no way Tom couldn't have seen Jerry jumping into the invisible ink bottle.
- Frame-Up: In order to dispose of Tom, Jerry, while invisible, hits Spike over the head with a golf club while he's sleeping before handing it to Tom. Upon seeing Tom with the club, Spike thinks Tom was who hit him with it, resulting in Tom running for it with Spike chasing after him while thwacking him with the club.
- Hero Antagonist: One of the few shorts where Jerry is the antagonist.
- Invisibility Ink: Invisible ink makes Jerry invisible.
- Invisible Jerkass: Jerry mercilessly takes advantage of his invisibility.
- Misplaced Retribution: Tom ends up being chased away by an enraged Spike after Jerry smacks him with a golf club.
- Oh, Crap!: Tom, when the invisible Jerry hits Spike with a golf club.
- "Scooby-Doo" Hoax: Using his invisibility, Jerry plays a bunch of pranks on Tom to drive him crazy: drinking his milk, giving him a hot foot, and even walking over the piano keys to produce a spooky chord. His cover is blown when Tom sees his shadow while he's eating a banana and realizes the trick.
- Screams Like a Little Girl: Tom's scream of pain when he gets hit in the butt with a golf club is much higher-pitched than normal.
- See the Invisible:
- Tom sees invisible Jerry's shadow while the latter is eating and manages to hit Jerry with a book.
- Tom tries to find Jerry by throwing flour on the floor so that Jerry would leave footprints. When he does, Tom tries to hit him with a frying pan. Moments later, the words "Missed me" appear on the flour. Due to flour still being on his feet when he runs out of the kitchen, Tom is still able to follow him.
- Throw the Book at Them: When Tom sees Jerry's shadow, he takes a book and smashes Jerry with it.
