Season 4 — Episode 7
Pacific Island: Panama
Bear Grylls heads west off the Panama coast into the Pacific and is dropped near a deserted island. There's no fresh water so he uses a water still to make drinkable water from the sea water, goes spear fishing to catch triggerfish and free dives for oyster. Bear builds a raft and sets out to sea. He finds a small island covered in guano and cactus. At the top he discovers a boobynest with two eggs. Back on his raft he performs an enema. It's not pretty but could save your life in an emergency.
