The Giant Cave Bear is a large version of a real life extinct animal also called the cave bear.
While exploring the deadly jungles of Skull Island, Carl Denham and soon-to-be lover Hilda were suddenly ambushed by th giant cave bear. The towering mountain of flesh, fur, and claws looked to devour the humans. Rushing in to help them, Kiko attacked the cave bear. Back and forth the mammals of Skull Island battled, but the superior intelligence of the ape tilted the battle to his favor. Grabbing a gigantic log, Kiko hammered the trunk into the bear’s body until it fled the scene.
