The boys decide to set up a hammock in the middle of the ocean. They're not sure what they're going to do with the food they've been given, so they decide to go for a little ray-fishing. The boys are excited about the prospect of catching some fish, but they'll have to wait until they'd set up camp before venturing out into the wild. They decide to use a harpoon to kill the ray, but it's not strong enough to pierce the ray's dorsal fin, which is its stinger. The harpoon will help protect the boys from being stung by the ray.
