When the Horn of Evil was stolen from Trolla by Trap Jaw and Clawful, Yukkers accompanied Dree Elle to Eternia to warn Orko and his friends. While there, Yukkers could not resist having fun at Orko's expesne, creating tension between the two. Although his intentions were innocent, Yukkers nearly destroyed all of Eternia when his pranks caused him to accidentally blow on the horn, unleashing terrible evil. After Orko and Dree Elle managed to reverse the horn's disastrous effects, Yukkers learned a valuable lesson about playing safely before returning home.
