An undead yeti that ( before he was undead ) led an army of yetis from the Gloomberg Mountains who one time was dumped by the Lindworms of molten lead and boiling tar. Then, one day Skullop's army suddenly found themselves on the borders of Nairland. They reached a part of in which consisted of sand. However, Skullop's army of yetis did not know that this sand wasn't just any regular kind of sand, but was actually Cogitating Quicksand. Right when Skullop was about to give the signal to advance across it, he heard a strange voice in his head.
