Trixie's in a mischievous mood, but her ghostly pranks get everyone angry at her, and give Robbie an idea to scare the kids out of learning by dressing up as a ghost. With everyone trapped in the school and the kids initially not believing Trixie's story, Ziggy's slippery, slimy sportscandy surprise experiment may be the only thing that can stop Robbie's plan!
This episode contains examples of:
- Call-Back: Even though it isn't the same one, Robbie's ghost disguise is very similar to the one he wore back in the episode "Haunted Castle."
- Shout-Out: The entire episode is one to the Ghostbusters franchise, complete with slime.
