With a new device called the Stone Ray under his control Skeletor is able to create monstrous beings from rock. He rapidly builds an army which He‑Man is initially able to defeat before the royal palace is destroyed, but more monsters are created. During the ensuing battle Buzz‑Off discovers Skeletor's creatures dissolve in water. He‑Man diverts a river and drowns the rock warriors. Skeletor tries again by creating a giant rock warrior, but this is smashed by He‑Man. Look out for the red Battle Ram sled in the middle of the story. This tale is quite fun and well illustrated.
