Here's a clip from the 1989 Real Ghostbusters' prime time Halloween special,
The Halloween Door. This special was pretty out there, the Ghostbusters actually perform a musical number in tribute to Halloween (and yes, those are the real voice actors singing, lol):
Great message in the special too, about how we use Halloween to help children not to be scared of monsters and ghosts (this was in direct response to parents' groups at the time objecting to the holiday as "too scary" or even "Satanic"). One the best lines in the episode, "The first rule of the fanatic. When you become obsessed with the enemy...you become the enemy!" (Sometimes the GB fanbase might want to keep in mind going forward, hehe).
