S1E51 Dree Elle's Return

Clawful and Trap Jaw have successfully taken the ‘Horn of Evil’ from Trolla and brought it back to Eternia. Sensing the threat, Dree Elle, along with her playful little brother Yuckers, rushes to warn Orko and his friends about the impending peril. The wicked pair plan to unleash the horn's dark magic on Castle Grayskull, but the situation worsens when Yuckers’ affinity for practical jokes not only annoys Orko and Dree Elle but also lands them in serious trouble.
