The Real Ghostbusters - Season 5 - Eps 9: The Halloween Door
The Ghostbusters are confronted by Crowley (Michael Rye) and his group, who want their help in ending Halloween. The guys turn him down, but one of their PKE meters is stolen and used by Crowley to accomplish his goal. Unfortunately, all he does is break a seal, opening our world to numerous ghosts – including the huge, rampaging Boogaloo (Brian O'Neal) – and giving the Ghostbusters a lot to handle on Halloween night.
