Pi invents a rocket to take himself, Yam Yam and Ruddle to the moon. Yes that’s right, the moon! Whilst they are packing a sheep accidentally climbs on board, unknown to the rest of the crew. After they land on the moon’s surface each of the Boblins goes off to explore the new world, whilst the sheep manages to put on a pair of rollerskates that was packed by Ruddle and starts his very own roller disco by going up and down the moon hills, accidentally knocking Pi onto his back, skating off out of control. Ruddle and Yam Yam go off in the moon buggy and rescue them both in the nick of time, just before they go over a big moon cliff. They all then blast off back to Rainbow’s End just in time for tea and cakes.
