Old Jack and Salty are having fun dancing. Jack spots that Salty is just like his shadow - she does the same things as him at the same time. Jack remembers a time when he and Little Sailor Sue danced on the beach with their shadows! In the rockpool, Sheena the Shrimp is dancing - but the music from her musical rock keeps stopping. Sally the Starfish thinks they should play musical statues, giving the rockpoolers a chance to try out their very fancy dance moves. But who is the huge dancing friend that Sheena has found?
