Funland (1989)

Plot: A growing group of leering, belligerent punks known as the Trolls are intimidating fun-seekers at the coastal amusement park Funland, and some of the local teens blame the Trolls for a series of missing persons and decide to fight back late one night. But what’s really behind the disappearances is waiting for them all in the funhouse... The basic premise of Funland is that a group of teenagers (the tollers) are sick of all the bums (trolls) hanging out on the boardwalk – Funland. These bums aren’t just homeless people, they are crazy. So they take it upon themselves to start hunting the trolls after the park closes. At first its just innocent little pranks, but then the pranks turn deadly.
