At some point, Calamari stole Houdini's act. In the 1980s, after Calamari was prevented from fleeing the Magic Theater by the Ghostbusters, he shoved his luggage cart at them. Egon Spengler discovered Calamari's trunk had a false bottom. In it was Houdini's notebook. Ray Stantz returned the notebook to Houdini's ghost, who then flew into the Cabinet of Mystery and released Irving and Peter Venkman.
- Due to the episode being animated in Japan, the notebook front and back covers are mistakenly shown backwards.
