Trivia

 * This episode marks the debut of that obnoxious and conniving weasel-like imp called the Varmint.
 * When the Star Teens' moms get turned into teenagers, Danny Phantom fans will get to hear Trixie (Ella's mom), Samantha (Sandra's mom), Judith (Felicia's mom), Elena (Tanya's mom), and Heather (Sheila's mom) who all sound like Jazz Fenton, Sam Manson, Star, Paulina, and Valerie Gray. When Debbie (Inidra's mother) is turned into a teenager, her voice sounds like Heather Adams of "Denver the Last Dinosaur". Daphne (Lisa's mother) is the only mom being turned into a teenager who is voiced by a different actor, Janice Kawaye (the actor who voiced XJ9 on "My Life as a Teenage Robot").
