The Real Ghostbusters
Janine's Day Off
S5 E9:
Egon goes with Janine to see her relatives, while Peter, Winston and Ray have to deal with imps at the firehouse. But trouble starts when the imps merge into a gigantic monster that rampages across New York, and Janine, Lois (the temp secretary) and Slimer have to deal with a trio of ghosts who find one of the Ghostbusters proton packs and start shooting up the already damaged Firehouse.
