''PSHAW!'' or ''Powerpuff School Hijinks And Wackiness'' is a ''PowerpuffGirls'' fanfic, with various stuff from [[MegaCrossover other Cartoon Network shows]], by Andrew Joshua Talon, well-known for his fanfics "Hands", "Progress", and other various fics. It was based upon back and forth between him and The Sage of Toads, who is known for his own fanfics ''Fanfic/{{ARSENAL}}'', ''Fanfic/TheKeyToASuccessfulInterview'', and ''Fanfic/BeautifulDestroyerSailorMoon''

It takes the cliches of teenaged Powerpuff girls fanfiction, and gives it its own unique spin. With a number of shots taken at ''Webcomic/PowerpuffGirlsDoujinshi'' for good measure.

!!Tropes associated with this fanfic include:

* ActorAllusion: More than one joke is made about the Narrator having the same voice actor as the Ice King.
* BadassGrandpa: Prof. Utonium's father is none other than Samurai Jack. He cements this by giving the girls a challenge in a spar with them.
* BonusMaterial: Spacebattles has a thread for this fic; like AJT's other fics on that site, it has rough drafts, omake scenes, and other various info.
* FunWithAcronyms: As usual for a Sage of Toads production, the title.
* OriginsEpisode: Chapter 4 explains how the PPG changed from their original look(as they hadn't aged a day until what happened in that chapter.)
* TakeThat: One of the best counters ever made against the PPG/RRB pairings is given in chapter 1.
** Someone suggested that [[Franchise/ScoobyDoo Scrappy-Doo]] and [[WesternAnimation/TheThirteenGhostsOfScoobyDoo Flim-Flam]] be [[RetGone erased from existence]] by [[TheRockyAndBullwinkleShow Mr. Peabody]]. [[TrollingCreator In response]], it was [[WordOfGod decided]] that instead, the now adult Scrappy and Flim-Flam work as P. I.s in Hawaii.
* ShoutOut:
** In Chapter 4 we get a whole bunch. Townsville's Project Yggdrasil with its' underground base, mobile buildings and large number of automated defenses around the city are all references to Anime/NeonGenesisEvangelion. The [[spoiler:launching of the Powerpuff Dynamo against HIM]] is basically one big shoutout to the battle with the Fourteenth Angel and Tabris/Kaoru's descent into Terminal Dogma.
*** In the same chapter the [[spoiler:self destruct code for the Powerpuff Dynamo]] is very similar to the one used for the Enterprise in ''Film/StarTrekIIITheSearchForSpock''. And Mojo Jojo's HumongousMecha is named [[Anime/TheBigO Big Jojo]]. Mojo even summons it like Roger Smith does Big O.
