The Real Ghostbusters
Egon On the Rampage
S4 E8:
The Ghostbusters seem to have two problems: a newscast at their headquarters and Egon's soul being swapped with a demon's thanks to the reporters playing with their equipment. Now, Ray and Winston have to get Egon's possessed body back to the Firehall while Peter goes into another dimension to retrieve Egon's soul, before the change is permanent.
