This episode, along with The Cuckoo Clock of Doom, had a special opening theme on its original premiere in which there was a ten-second remix when R.L. Stine walks through the grass with the briefcase. When the G passes the dog, the music is played with a different instrument. There were also different scenes from the show when the door opened. The two episodes were also the only ones whose titles were in white instead of green.
Adapted into Goosebumps Presents Book #1.
This episode is based on Goosebumps book #08.
Mr. Mortman's actor, Eugene Lipinski, later voiced Rocky in "Night of the Living Dummy III".
