Synopsis
One morning, Mrs. Howell discovers her diamond brooch missing, unaware it has been taken by a gorilla attracted to her perfume on it. She gets abducted by it as a result and the other Castaways try to rescue her. Eventually, the Professor realizes its attraction to her perfume and decide to use it to lead the gorilla into a trap. When Gilligan runs back to get it, he accidentally turns the open bottle upside down and douses himself with it. When he gets back to the Professor and Skipper, the scent on him is over-powering and the gorilla abducts him in exchange for Mrs. Howell. Now, Gilligan needs to be rescued, and as the Skipper and Professor try to mix a similar perfume, Gilligan escapes back to camp; the gorilla having run off with a female gorilla.
