2 - 18: Prehistoric Ice Man

Kyle and Stan find an ice man frozen in a cave, and argue over their discovery. Dr. Mephesto determines the ice man is not as ancient as they'd hoped, but builds him a habitat to simulate his original time period. They realize he'll just never fit into their era, so they try to find the perfect place for him.
