Once on the island, it turns out that Muffy has set up a variety of pranks throughout the mansion, ranging from simple gags such as a whoopee cushion and dribble glasses and exploding cigars to more complex and disturbing pranks, such as an audiotape of a baby crying in someone's room and heroin paraphernalia in a guest's wardrobe. In spite of this, the group try to relax, until Skip goes missing, and Kit catches a glimpse of what looks like his dead body. Soon, Arch and Nan also go missing. During a search for the pair, Nikki falls into the island's well, where she finds the severed heads of Skip and Arch, along with the dead body of Nan. The remaining group members then discover that the phone lines are dead and there is no way to get off the island until Monday.
