Once Upon A Whine is the 18th episode of Sabrina the Animated Series.
While Sabrina is cleaning the house, she accidently brings Cinderella into her bedroom. She discovers that Cindy is a whiney, lazy, sloppy girl. When Sabrina tries to send Cindy back she accidentally sends Harvey to Once Upon A Time Land! She must return Cinderella back to where she belongs and retrieve Harvey before Uncle Quigley finds out she didn't follow the rules and before Harvey is stuck in Once Upon A Time Land forever.
The episode's title is a take on the phrase "Once Upon A Time", which are the first words at the beginning of fairy tales.
