"Piper and Kayla love to move. They ride bikes, glide on ice, swoosh down mountains and much more - each in her own way. While Piper pedals her tricycle with her feet, Kayla uses her hands to move her trike forward. While Kayla coasts across the ice on a sled, Piper sails along on skates. Join Kayla and Piper as they play together, explore their world and make new friends."-- Provided by publisher.
