S01E10 Waiting For Watubi

As the Skipper is digging, he stumbles upon a carved idol of a Tiki God. Convinced that he has awakened the spirit of Watubi and brought a curse upon himself, he fears for his life. In an effort to help, Gilligan dons a costume resembling Watubi and puts on an elaborate dance, which he believes will break the curse. The performance turns out to be quite an earth-shattering event!
