Based on Piano Lessons Can Be Murder, book #13 of the original Goosebumps series.
Jerry discovers an old piano in the attic of his family's new house, only to find it's haunted by its former owner.
The episode provides examples of:
- Cool and Unusual Punishment: Unlike the book, Mr. Toggle's fate is shown here. As punishment for terrorizing Jerry and being a lazy student when he was younger, the ghost, revealed to be Mr. Toggle's piano teacher from his youth in this version, makes him practice the piano in the now-derelict Shreek School's recital hall for eternity.
- Leitmotif: Beethoven's Moonlit Sonata, which becomes a frightening one when the disembodied hands start banging on the keyboards.
- Named by the Adaptation: Jerry's mother is given the first name Adele, while Mr. Toggle is given the first name of Andrew.
- Race Lift: Kim Li Chin, who is implied to be Asian by name and appearance in the book, is African-American in the episode.
