Eva Grubb

Bio
Eva Grubb is a visitor to the island who came seeking isolation from others because of her plain looks. Rejected by potential boyfriends and suffering from an inferiority complex, she saved her money and bought the boat to live by herself in exile, but whether she found the island on purpose or by accident is unrevealed. When docking on shore, she is met by the Skipper and Gilligan, who plead for her to rescue them. Instead, Eva tells Gilligan and the Skipper they can have her boat, providing they do not reveal the island to anyone. The Professor considers Eva irrational and wants to get her help, but after hearing their plans, she attempts to hold everyone hostage on the island, as well as sabotaging the boat by removing the spark plugs.

Ginger and Mary Ann try to help Eva by giving her a beauty makeover, with the Professor creating a special shampoo for her hair. Afterward, everyone is shocked that Eva looks exactly like Ginger! With her new look, Eva fools Gilligan, but realizes she'll be overshadowed by Ginger, and she tries to replace her. She knocks Ginger out with a coconut and gags and ties her up. After Ginger regains consciousness, she tells her about her evil plans.

The Howells have a party in Eva's honor, while she rushes back and forth changing clothes and breaking her eyeglasses in the process. The real Ginger eventually frees herself and exposes Eva's evil plans. Convinced she could still replace Ginger, Eva sneaks away overnight aboard her boat, leaving behind a note calling the castaways "Suckers." At the end of the note, she calls herself "The New Ginger Grant." Devastated, Ginger cries, and when Gilligan mentions getting some grub, Ginger answers: "Don't you ever mention that girl's name again!" Eva's current whereabouts is unknown, and it's unlikely she was able to replace Ginger.

Trivia

 * Eva Grubb was played by actress Tina Louise in a dual role; a stand-in played her in some scenes.
 * Tina Louise received a double credit for this episode. However, unlike many who were credited at the end of the episode, the opening scene shows "Tina Louise as Eva Grubb".
 * Despite Eva's plans to achieve fame and fortune, it appears she either failed in her attempt or was discovered as an impostor. In "Rescue from Gilligan's Island", Ginger found her career still stalled despite what publicity she had received from her rescue. Furthermore, in a later episode, Tongo the Ape Man mentions recognizing Ginger who had vanished.
