The Horn of Evil has been taken from Trolla by Clawful and Trap Jaw. On Eternia at the City of Colmay Adam, Cringer and Man-At-Arms are waiting to destroy a meteor shower. One meteor escapes their firepower, so He-Man and Battle Cat save the city. Orko is the only one at the Royal Palace when Dree Elle and Yuckers appear in the pyramid. At Castle Grayskull Clawful and Trap Jaw use the Horn of Evil. The Sorceress appears but is overcome by the power of the horn.
Orko arrives and takes the Horn of Evil from the villains. Orko and Yuckers are captured, but Dree Elle escapes and informs Adam, Cringer and Teela. They arrive to help Orko and Yuckers. He-Man shows up shortly after, with Yuckers accidentally activating the Horn of Evil. Dree Elle finds a song behind the skull on the horn. Orko and Dree Elle unite their voices and sing the song.
All of the evil magic disappears and the Evergreen Forest is restored. Back at the Royal Palace, King Randor thanks Orko for his bravery, and Yuckers learns his lesson.
