Hordak schemes to lure He-Man into his Slime Pit trap, and make him his mindless slave forever by sending two Horde troopers to steal the Great Book of Wisdom from Castle Grayskull. He-Man's quest to recover the ancient tome leads him, and his allies Stonedar and Rokkon, deep into the Fright Zone and into Hordak's clutches, at the mercy of an army of hundreds of strangely-designed Horde troopers (see accompanying picture). In the end, Stonedar and Rokkon change to their meteoroid forms, and mow down the squads of troopers row by row. He-Man recovers the book and Hordak takes a dip in his own Slime Pit!
