It’s “The Powerpuff Girls: Twas the Fight Before Christmas” – Review (2003)

Townsville is getting ready for Christmas, which is in two days. The children at the PowerPuff girls’ school, including the girls themselves, are getting into the Christmas spirit. Princess Morbucks is her usual spoiled self. The PowerPuff girls put her down for all the terrible things she’s done. Princess Morbucks gets angry and asks her servants if they think she’s naughty. But they won’t answer. Desperate for her wish to become a powerpuff girl, Princess Morbucks sneaks into the north pole and discovers that she is on the naughty list. And she’s the only one. So she alters the list titles, making herself “nice” and everyone else “naughty”.
