Trivia

 * The scene where the Star Teens spray Gwendolyn’s potion to turn Queen Vampira into a good queen is similar to when McNasty, Bones, and Lumpy get reversed by the Mean Machine in “Pound Puppies and the Legend of Big Paw” and Peter Palette pours the magic potion into Emperor Spine’s mouth which makes him a good flower king in “The Elmchanted Forest”.
 * The Star Moms, the Little Star Kids, and Gwendolynda all return.
