Troll Bridge

A young Troll leaves his tribem 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 an 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.
