Steve's epic adventure reaches Cuba, a colourful Caribbean island with a secret deadly side. First up, Steve must overcome his fears to get in the water with a lethal prehistoric predator, the american crocodile. Next, Steve explores a cockroach-infested cave in search of a giant bat-eating snake. Finally Steve dives Cuba's pristine coral reefs as he goes head-to-head with a goliath grouper. This monster fish weighs more than Steve and has a mouth that can gulp down whole lobsters and, as it turns out, Steve's arm!
