Pebbles and Bamm-Bamm are at the beach, when they go into a world ruled by a King Crab, who happens to have extreme shyness. Problem is, King Crab's shyness is being exploited by the chaimberlain, who plans to overthrow the king. Pebbles and Bamm-Bamm tries to help the King Crab, but the chaimberlain catches them and tries to feed them to a dragon. But King Crab eventually overcomes his shyness, defeats the dragon, and the evil chaimberlain falls into the moat while ranting in defeat.
