Animation. Arthur and the gang try to set world records, and go on a class trip to a dark cave.
Why is Buster walking backwards and Muffy not talking? They are trying to set world records - everyone tries to go it alone, but Arthur and the gang discover that working together more readily creates success, fun, and the world's largest pizza!
Arthur thinks his class trip to the Clark Caves will be really cool, but he is concerned that it will be dark, too.
