Halloween, 1999. Two goblins sneak into the Firehouse and make their way to the Containment Unit. They once again free their master Samhain, who brings several ghosts from the containment grid with him, including the gremlin, the Boogieman, and the sisters Banshee and Syren. Samhain was very mad and left his minions to attack the Ghostbusters. They were all recaptured and restored to the grid. The original Ghostbusters tracked down Samhain. Samhain called for his goblin minions, only for them to be captured. Samhain was then trapped and restored to the Containment Grid.
