"The Powerpuff Girls' Best Rainy Day Adventure Ever"
During a romantic day in Townsville, Harry Pitt (the boy who is believed to have "cooties" at Pokey Oaks Kindergarten) starts chasing everyone around, trying to kiss them. Everyone desperately flees the mayhem of Harry Pitt. It just so happens that Mojo Jojo oversees this event. Determined to find a perfect weapon for his crimes, he meets Harry and they both team up to terrorize Townsville, later gaining the help of the Mafia. Their crimes end up so successful, that they are able to hold the mayor hostage. When the girls arrive at the scene, Mojo lets open a trap door of which they fall into and then Mojo drops Harry down through the trap door. Harry once again starts chasing the girls, trying to kiss them. Soon, Blossom ends up being kissed by Harry, but nothing happens to her. Once she and her sisters discover that cooties aren't real, they kiss Harry all over his face, fly out of the trap door and beat up Mojo. Mojo goes to jail, but this time, his prison mate is smiling creepily at him. This can only mean really bad news for Mojo.
- Due to the fact the girls kissing the Rowdyruff Boys is what destroyed them, their fear of cooties is possibly out of fear the same may happen to them.
- Both the movies The Godfather and Scarface are referenced in this episode.
- A couple showed in the beginning of this episode can also be found on a poster in the episode "Mime for a Change".
- This is the second episode were a background character plays an important role. The first one was "Paste Makes Waste".
- Although this episode was produced during 1999, this episode is the first episode to feature the familar and well-known 2000 circle designs of the girls (designed by Chris Battle), which will remain in regular usage (alternating with the 2000 oval designs) until "Stray Bullet".
- This episode shows a slow motion scene for the third time. The first two being "Uh-Oh, Dynamo" and "Mo Job".
- Moral is that there is no such thing as cooties, and not to believe everything that you hear.
- In one scene where the new place of residence for Mojo Jojo is presented the logo of the building is spelled "Mojo's Managemint".
