As Ugh begins his day like any typical caveman (battling a stegosaurus), he, while escaping by means of a handy vine, ends up crashing into the habitat of the tiny Ant Warriors. They end up doing a Lilliputian-number on the Ugh-Gulliver as they tie him to the ground. Led to the scene by Bronty, Dino Boy arrives just in time to free Ugh. They then join forces with the Ant Warriors to defeat their common enemy... a rampaging giant sloth bear.
