Banner just came to the forest and has no idea that he should pick up supplies for the winter. Instead he has fun walking through the trees where he meets many animals, including two mischievous mice, that seem very appetizing to him. Fact, that he tried to eat mice is so funny, that they can't stop laughing. But that's not all. Banner is suspected of stealing supplies for the winter from another squirrel Acacio. Banner investigates this case and manages to discover who the real thief is.
