If you go to the top-left corner of the map you see an island shaped like a square. If you fly a plane over the island your plane will explode, causing you to parachute down to the beach[if over it]. You will see a search sign on the beach with an arrow pointing to the jungle and you'll find the hatch from "Lost." It is even said by people that you can hear the smoke monster in the background.
Look for a billboard that features the face of the dictator Baby Panay. When you find one use the grappling hook to position Rico directly over his face and then press 'Action'. Rico will now draw glasses and a mustache over the face.
aim at a person, grapple them but hold down the grapple button, then aim at a tree or building and let go of the grapple button. they should be hanging from the tree\building. then just press the B button to swing the grappling hook at them. sadly no candy comes out. only blood.
This can be found at coordinates X7392, Y16151 (there is also an armor piece near the balloon). To ride the balloon shoot off the sandbags and steer it by waking in the basket. Unlike other vehicles the hot air balloon can be used to fly over the Lost island without getting destroyed.
This purple weapon which can be equipped is found in the Lautan Lama Desert Territory, South of Gurun Lautan Lama Gamma.
