0Get ready to meet a new rock group! From zippy, little pebbles to big strong boulders, the rocks (and their ladybug friend) get together to play and roll around their favorite hill, only to find that one of their friends, Ricky, can't roll with them. Unlike all of the others, who are all round, Ricky can't roll because he's flat on one side. Determined not to leave their friend behind, the rocks and the ladybug set out to help Ricky roll around - one way or another.
