Plot[]
A young troll leaves his tribe, goes exploring and ends up in New York. While he has a good time, his tribe takes over the bridge and threatens to destroy the city if he isn't returned by sundown, using a group of flying, fire-breathing birds. The Ghostbusters have a hard time catching the troll, but when they do, they can't stand to separate the party animal from the city.
Instead, they convince the other trolls he was turned into a statue when their proton stream hit him. While the other trolls leave, the Ghostbusters send the young troll to a friend out of town.
