As the Ghostbusters and Katarina Novachenka set off to confront Yibb-Tstll and his cult, Slimer/Animated set off on a 10,000 mile flight back to the Firehouse and retrieve Big Trouble from Egon's laboratory. Slimer brought it to Egon just in time. He managed to assemble the four pack configuration but someone needed to set the 20 second countdown and toss it down the pit Yibb-Tstll was coming out from. Peter Venkman valiantly volunteered and activated Big Trouble. Yibb-Tstll was returned to a state of dormancy and the surrounding area caved in.
