The Midnight Snack

Tom's chasing Jerry when he runs right into a sleeping dog and the two of them must work together to fend him off.

Tom, whose appetite was whetted by a radio cooking program, wants to make a meal out of the pet goldfish. Jerry, who is friends with the fish, does what he can to thwart their feline foe.

Tom subjects Jerry to his usual harassment; but the cat finds a new enemy, and the mouse finds a new friend, in the canary of the house.

Mammy Two-Shoes tells Tom and Butch that the cat who gets rid of the icebox-raiding, breadbox-invading mouse (Jerry) is the one who can stay.

Mammy Two-Shoes replaces Tom with a younger cat who is a lightning-quick mouser. Tom and Jerry form an alliance in order to get rid of this dangerous newcomer.
