Peep falls asleep one lazy afternoon and dreams that he's a butterfly, Chirp's a duck, Newton's a squirrel and Quack's a turtle. Guess who's not happy with this arrangement? Chirp moves into a glorious sand castle she found on the beach. Of course, Quack immediately wants a castle of his own - only HIS must be bigger and better than Chirp's. Then, Pocoyo finds a radio. Pato does his funny, funky dance and Elly demonstrates her delicate ballet style.
