The Country Mouse (1935) (SVTFOES5 Reissued 2020 produced by Phineas and Ferb Cartoons Inc.)

A tough mouse named Elvis is punching a boxing bag, showcasing his skills to a crowd including Beans and Porky. Elvis wants to become the heavyweight champion of the world. He shows his skill to his grandma by punching a scarecrow, but the scarecrow's arm holding a stick bops Elvis in the head. His grandma tells him to do his chore of chopping down wood. Elvis slides through each side of the tree using an axe, but his grandma isn't amused and shows off her own strength, which is remarkably better than Elvis'. Elvis states that he wants to be a fighter, but his grandma just brings him in the house in frustration.

That night, he sneaks off to go to the game in the city. His match is a bulldog, and Elvis proves to be extremely weak against him. Back at Elvis's house, his grandma just so happens to hear the entire wrestling match on the radio, and she goes after him so she can stop him fighting. She cycles to the game, and punches the bulldog to a knockout, wins the match and receives a crown. Despite her victory, her work is not done yet; she grabs Elvis' ear and spanks him as punishment for sneaking out of the house.
