The trail of Bunnicula clones that occur during the sequence where Bunnicula sees all the clones for the first time is inspired by a part of the dream sequence Pooh had where elephants would stand in a horizontal line.
The Bunnicula clones watch a show called The Real Businesswomen of Atlanta, where one of the women tries to figure out who used her toothbrush. This is done to make fun of the actual show.
