Later, near the island's campground, they spot a dangerous-looking creature that looks like a cross between a monkey and a cat. Jesse sends a photograph of the animal to Jasper Callison, a retired biology professor and head of the Society for the Search for Unknown Animals. Jasper decides to investigate, and calls on his old friend Pete, a retired biologist who has worked with him before. Once arriving on the island they are befriended by Sheriff Tillman Dunn who shares in their adventures.
