Topsy-Turvy

Topsy-Turvy is the 78th episode of Gilligan's Island and the tenth episode of the third season. It aired November 14, 1966.

Synopsis
Head-hunters land on the Island pounding their war drums, and the Professor seeks out a cave to hide everyone until they leave. Unfortunately, Gilligan runs straight into a tree, and the whack to his heads flips his vision upside-down. The Professor thinks he can fix his vision with the curative powers of the keptiburra berry growing on the island, but Mary Ann is too afraid to look for them with the pounding drums from the jungle. However, Gilligan notices the sounds have stopped, unaware the head-hunters are still on the island despite their broken drum. Ginger and Mary Ann search the island for the berries unaware the head-hunters are still prowling around and trying to capture them. One of them tries to attack Gilligan, but he is scared away by the approaching Howells. After the Professor creates extract from the berries, the berries succeed in flipping Gilligan's vision back, but it also doubles it so Gilligan sees two of everything. The Professor meanwhile warns Gilligan his skewed vision might result in hallucinations, and when he starts seeing the head-hunters, he thinks they're hallucinations. However, the head-hunters start getting frustrated with their failed attempts to capture Gilligan. They capture both the Howells and the girls, and after the Professor fixes Gilligan's vision with water to dilute the strength of the berries, both he and the Skipper get captured. Gilligan flees into the jungle chased by one of the head-hunters, but realizing he's out-numbered, he returns with the keptiburra extract to trick them into thinking they're out-numbered. He comes to rescue everyone pretending to drink the extract which the head-hunters take away from him to drink themselves. As the extract takes control, Gilligan frees everyone who appears as an army to the head-hunters, terrifying them off the island. Afterward, everyone is so appreciative of his clever heroism that they give him gifts. Mary Ann gives him a coconut cream pie, but Gilligan is so excited that he drinks the extract again so it looks like five pies. However, this makes it hard to eat the one; he pounds the table and causes the pie to smack the Skipper into the face.
