Sibling Rivalry is a YTV All-Stars spoof to the Simpsons song of the same name. It stars Ash and his family (with Fabiana as his stepsister). The 12 Mean Girls (Lexi Bunny, Fiona Von Steig, Marie "Rogue" D'Ancanto, Mel Blake, Brittany Wong, Zuzu Boyle, Mackenzie Hollister, Malinda Doe, Suzi, Pacifica Northwest and Hope Todd and Rosalina Daily) also star.


  • With Fabiana as a stepsister to The Ketchums, everything seems fine until Mary and Ash get into a rivalry, as they perform a song about siblings. After the song ends, The Twelve Mean Girls arrive to stop the ruckus, but Francesca kicks them out.
