It's About Time

Hector and Mac have their first day in the past and the caveman think they are evil spirits. They make good with a caveman's son and save his life. He wants to be an adult and the custom is to spend a day in the jungle alone. Hector and Mac suggest that instead of having this ritual they throw him a birthday party instead.

Mac and Hector need to find copper to repair the space ship. Unfortunately, the only copper they can find is around Boss's neck, in his necklace.
