Episode 2

The Walshes are still in Mexico and still on the side of a mountain. Can they complete the final part of the challenge, which requires Bradley to swing across the top of the mountain with nothing but a terrifying drop below him? Once recovered, the father and son head toward Mexico's coast, where Barney takes his dad inside a pitch-black cave that's home to snakes and thousands of bats. They also have fun at a waterpark before joining the cast of Cirque du Soleil.
