The fan appears in the episode segment, Night of the Living Dull, after Gogo Dodo, Sphinx, The Elephant and the other characters from Wackyland run into an old cabin and keep getting bothered by dull people. They try to escape from the back door, only for the fan to appear and block the way out. After he talks to them, Gogo and the others run over him to escape.
- The Fan is based on Dennis Falk, an actual overly-obsessed fan the production team encountered while working on Tiny Toon Adventures. He was a stalker who sent Tress MacNeille disturbing letters which caused her to fear for life and cancel any convention appearances she was planning to make around where he lives.
