Sylvester can’t find a stirring mouse on Christmas Eve, and is overjoyed when Santa brings Tweety to Granny as a present. Sylvester switches Christmas-gift tags so he receives Tweety instead of a toy. Granny is puzzled when her gift is a rubber mouse, but then realizes what has happened when Sylvester burps up Tweety’s feathers. Tweety distracts Sylvester with another gift: a large bulldog, which devours the cat. Granny promptly beats the dog’s behind until Sylvester is spit out. He resumes his ploys and torments of Tweety until Granny has had enough.
