The city of Townsville is celebrating on all of the girls' heroics. The Mayor decrees that this day will be known as "Powerpuff Girls Day", commemorating a statue in their honor. Blossom gives a speech, promising that as long as the girls are in Townsville, evil and wrongdoers will not prevail.
Just then, a slime monster starts terrorizing the city. The girls try using their powers on it, even the Ice Breath, but nothing works. However, they try to perfect their Furious Fiery Feline formation to burn it, but as soon as they descend, the monster catches the formed cat and hugs it--it was looking for its cat the entire time. As soon as the fire gives way, the monster causes more chaos in disappointment.
The girls look all over town for a cat, but they picked the wrong one. Bubbles uses her Supersonic abilities to lure all cats into the girls' current location. They show the cats to the monster, but it soon rejects them after noticing that the cat it's looking for isn't one of them. The girls quickly catch the cats before they plummet. Just then, Blossom notices that the cat it's looking for is in its back. Blossom shows the monster the cat, who looks rather disgruntled, and the monster caresses the cat and returns to Monster Isle with it.
So once again, the day is saved, thanks to the Powerpuff Girls. Now the only problem is what to do with the rest of the cats.
