Up at Bat

"Up At Bat" is the 71st episode of Gilligan's Island and the first episode of the third season.

Synopsis
While storing supplies in a cave, Gilligan is bitten by what the Skipper believes to be a vampire bat. He becomes convinced Gilligan will become a vampire. Gilligan's fear is perpetuated by the fact that he cannot see his reflection in Ginger's mirror which has lost all the silver on the back. After sleepwalking and trying to bite Mrs. Howell in the neck, he decides to flee camp, later having a dream that he's a vampire attacking his fellow castaways. However, the Professor discovers Gilligan was bitten by a fruit bat, and the skipper heads off to bring Gilligan back to camp.
