He-Man
visits his friends Stonedar and Rokkon. Unknown to He-Man, members
of the Horde are hiding at the village of the Rock People. There,
Grizzlor, Leech, and Mantenna take He-Man, Stonedar, and Rokkon
as prisoners. Hordak builds a Slime Pit from rocks, with the slime
casting a spell onto any victim. He-Man is put into the Slime Pit,
where its spell turns him evil. Hordak orders him to go to Snake
Mountain and finish off Skeletor (so Hordak can capture the planet).
Skeletor is in his Terror Claws, and He-Man manages to land a couple
punches on Skeletor. He-Man breaks out of his spell with the help
of the Sun Rock, an idol (or perhaps even a full-fledged deity!)
of the Rock People. He-Man realizes that he shouldn't be fighting
Skeletor and heads back to the Rock People. The three win a fight
against Hordak, who retreats back to Etheria.
