The Monster High girls team up to face an all-boys league in the roller-skating competition "Skultimate Roller Maze" after losing their crest and watching their school deteriorate. Led by Frankie Stein (Kate Higgins), Draculaura (Debi Derryberry), Clawdeen Wolf / Cleo de Nile (Salli Saffioti), Lagoona Blue (Laura Bailey), and others, the all-girls team faces skepticism from the boys but finds inspiration in their predecessor Robecca Steam. With newfound determination, they overcome injuries and opponents to emerge victorious and break the tradition of male-only teams, paving the way for a co-ed competition that promotes diversity and inclusivity.
