Arthur and Buster take the bus downtown together for the first time to Arthur's swimming lesson. During the ride, they are so busy talking, reading, and sleeping they miss their stop and wind up on the other side of town. Then they spend all their money on a snack of chocolatewinkies and strawberry soda. Will Arthur and Buster be able to put their heads together and find their way home?

With characteristic humor, this Arthur Adventure will keep fans on the edge of their seats while they watch Arthur make his way home safely.
