"The Invisible Mouse" is a delightful and different Tom & Jerry's cartoon. It features the usual cat/mouse chases and battles, but in a different way this time. Jerry accidentally falls in a bottle of invisible ink and is obviously very glad about this because he realizes that he can prepare lots of "surprises" for Tom, scare him, torment him and confuse him.
As much as it is weird, it's also very cool and funny to see what we can't see: Jerry invisible. It's amusing to see things lifting up in the air without seeing who's doing it (we know who, right?) - it's like those things had a life of their own or even almost like a matter of ghosts. It's equally amusing to see Jerry eating some candies and fruits while he's invisible. I really like that instrumental music which plays when he's not visible.
Some of the best jokes on this short are when Tom sees Jerry's shadow and slams him and even when Tom tries to slam him with a frying pan and Jerry writes "Missed me". I also like when Jerry drinks Tom's chocolate milk, becoming visible again and with a happy look on his face.
Overall, this short has the basic ingredients needed for a classic cartoon: humor, entertainment, fun and some nice artwork too.
