Personality
Igor is the assistant and possible bodyguard to Dr. Boris Balinkoff, an eccentric scientist who lives in a spooky castle on an island close to the Castaways. In his first and only appearance, he meets Gilligan and the Skipper who were brought to the doctor's island for mind exchange experiments. Somewhere behind the scenes, Igor switches bodies with Ginger who uses his brawn and superior strength to help the others escape and regain their true identities. In the end, Gilligan uses the machine on Balinkoff and igor, switching their minds with a dog and cat.
