Описание сериии:
From thwarting bank robberies and fighting monsters to saving endangered citizens all day, the Powerpuff Girls come back from a long day of crime fighting, but then the Professor tells them to do chores, despite the fact that they are very tired. So, to help them do crime fighting, they choose to create another Powerpuff Girl. They sneak into The Professor's lab, and they try to create a new Powerpuff Girl in the technique left behind by the Professor himself. Unfortunately, for lack of the right ingredients, they improvise; they use artificial sweetener instead of sugar, dirt and twigs instead of spices and they put in what they think is nice, including:
Crayons, books, lizards, flowers, computers, footballs, stuffed animals, calculators, a mackerel, more flowers, a compass, boxing gloves, a ribbon, art, bandaids, a smiley face, a globe and a knuckle sandwich (Buttercup punches the mixture).
Finally, as if it were a scripted accident, they add the accidental dose of Chemical X. The mixture explodes in the tradition of the opening sequence, but it creates a hideously oversized girl. The girls introduce themselves and try to think of a name since the girl can't speak very well. Buttercup named her Braces at first, but Blossom disagrees with her idea. Eventually, Bubbles finally comes up with Bunny, and Blossom and Buttercup seem to agree with the name. The girls tell Bunny what she has to do and they send her off to fight crime while they try and relax.
However, if only for vague instructions, Bunny misunderstands what she needs to do when being told to fight the bad guys and throw them in jail; unfortunately, Bunny interprets the police as criminals (anyone who has a gun) and ends up imprisoning them in place of the perpetrators. It is not until the girls see her on the news that they realize that Townsville is in danger. The girls seek her out in town, and as she wails on a police officer, they tell her that she has been bad and is not cut out to be a Powerpuff Girl. Upset, Bunny flies away.
Straight away, the girls are surrounded by all the criminals, including the newly released, and are overpowered by them. Up on a ledge out at sea, Bunny hears their cries and (reluctantly) flies to their rescue, attacking all of the criminals in a way that only the girls were known for and shouting that she has done good. But just then, with her body unstable, Bunny explodes and perishes in a blinding flash, leaving only a piece of her dress.
The Powerpuff Girls manage to recover from being attacked by every criminal in Townsville, thanks to Bunny saving them. As they wonder where she is, the piece of her dress she leaves behind drifts to the ground. The girls become rife with surprise and grief; Blossom surmises that Bunny was unstable and broke down into her original ingredients, while Bubbles mentions in her eulogy that Bunny was good after all, especially on this one occasion, and that they were the ones who were bad. And with that, they hang their heads in sadness as they mourn the loss of their "sister" in the street, with the girls' meanness towards her coming at the cost of her own life.
"And so, for the first and final time, the day is saved thanks to Powerpuff Bunny", as the Narrator weeps, and he sobbingly breaks the fourth wall by telling the viewers to go a commercial.
