Princess tries to steal Christmas from the children of the world, and the Powerpuff Girls are to the rescue.
When Princess Morebucks finds out that she's been put on Santa's naughty list (in fact, she's the only one on it!), she does a quick re-write, resulting with Bubbles, Blossom, and Buttercup with nothing but coal for Christmas! On top of all that, Princess gets the one thing she wants for the holidays: super powers! Now, the girls have to stop Princess and make sure that Christmas is saved for children everywhere.—Lex
It is the day before Christmas Eve and everyone at Pokey Oaks are excited about Christmas. Blossom, Bubbles and Buttercup discuss their lists to Santa, when Princess Morbucks comes and tells them that she wants Santa to make her a Powerpuff Girl. The real Powerpuff Girls inform her that she is on the naughty list and will not be getting anything from Santa other than Coal. Morbucks refuses to believe that, but no one wants to tell her that it is true.
On Christmas Eve, everyone is getting ready for Christmas and Morbucks takes her private jet to the North Pole, sneaks into Santas workshop and discovers that she is the only one on Santas naughty list, so she switches the lists and heads back home. Bubbles wakes up after hearing Santa and rushes downstairs to discover that he hasn't left any presents and has left only coal in their stockings. Using her X-Ray vision, Bubbles discovers that every other kid also has coal. In a panic, Bubbles wakes up Blossom and Buttercup and shows them what happened. They go to explain to Santa that it was a mistake, but are ambushed by Morbucks, who has been given Powerpuff super powers for being the only "nice kid".
They follow Morbucks to the North Pole, where they eventually crash into Santas workshop, destroying the place right in front of Santa Clause. Santa feels sad and disappointed that everyone bar Morbucks is on the naughty list and at first seems to be with Morbucks, but when she tells him who the other three girls are, he knows that the Powerpuff Girls are constantly helping people and making the world a better place, making them good. Morbucks throws a tantrum and insulting Santa and he has no choice but to put her name on the Permanent Naughty List and he strips Morbucks of her powers.
The Powerpuff Girls help Santa deliver gifts to people around the world, before flying back into bed, only to be awoken by the excited Professor Utonium. The girls tell him to go back to bed, before realizing that it's Christmas and they all excitedly go downstairs and open their presents.
