Junior Ghostbusters

Mrs. Stone

Mrs. Nakami



Reitman Junior High School


Slimer played around with a wooden paddle ball outside the Firehouse. It got caught in a passing motorcyclist and took Slimer along for a short ride. He became tangled in a pole and ran into the Junior Ghostbusters. Slimer asked them if they would like to play but they were waiting for the school bus. Slimer wanted to come along but Catherine alluded to someone called Stoneface not liking that idea. They revealed she was Mrs. Stone, the school guard. The school bus arrived and the Junior Ghostbusters boarded. However, Donald dropped a manilla envelope without knowing it. Slimer rescued the envelope before it was swept down into the sewers and flew after the bus.

The Junior Ghostbusters barely made it to Reitman Junior High School in time and were scolded by Mrs. Stone. She stopped Slimer and asked what his name was. Mrs. Stone didn't see him on the roster and forced him off campus. Slimer wasn't going to give up that easily and phased through an alarm clock. It rang at 9 am sharp. Stone spotted Slimer and tried to take him to the principal. Slimer flew away into a science laboratory. He bumped into a skeleton then hid in a fish tank with two frogs. Slimer disguised himself as just another frog and managed to fool Stone. However, Stone came back into the room. Slimer hid in the skeleton and greeted Stone. They both freaked out and ran away in opposite directions. The two frogs waived goodbye to Slimer.

Slimer wandered onto tennis court and quickly hid in an automatic server. Stone grabbed a racket and tried to defend herself from the volley of tennis balls. Slimer was eventually shot out and landed right on her face. Slimer apologized but called her "Stoneface" by mistake. Stone was enraged and continued to chase after Slimer. Meanwhile, backstage in the school auditorium, Donald informed Mrs. Nakami he lost the scripts. Nakami had no other choice but to disqualify the Junior Ghostbusters from the talent show. Slimer popped in and handed Donald the envelope he dropped - with the scripts inside. Stone tried to grab Slimer but he held onto the rope that raised the curtain. The entire curtain fell onto the stage and the students in the audience thought it was part of the show. They clapped and cheered, prompting Mrs. Stone to take a bow. She high fived Slimer and they bowed some more. The Junior Ghostbusters were surprised Mrs. Stone finally smiled.
