The Shrinky-Pig 2000 is a invention that was created by Professor Poopypants. It has the power to shrink things.
Perilous Plot of Professor Poopypants
Professor Poopypants intended to use it and the Goosy-Grow 4000 to solve the world's problems, however due to his silly name, nobody took him seriously and just laughed at his name. After he read a comic book George and Harold made that also made fun of his name, he decided to take vengenance by making the rest of the world change their name. After the professor used his Goosy-Grow 4000 to enlarge his Gerbil-Jogger 2000, he used this machine to make the school and the people inside smaller. When Captain Underpants grabbed the Goosy-Grow 4000 and tried to get it to George and Harold, the professor caught him with it and immediately used this machine to shrink down the Goosy-Grow 4000 and Captain Underpants. After Professor Poopypants was defeated, George and Harold used the Goosy-Grow 4000 and the Shrinky-Pig 2000 to revert everything back to their regular size. After the professor was arrested by the authorities, George and Harold kept this invention in their treehouse.
Preposterous Plight of the Purple Potty People
George and Harold attempt to use it to defeat their evil clones, but they are attacked by Captain Blunderpants and the Shrinky-Pig falls into the hands of Evil George and Evil Harold. After Blunderpants is defeated, Evil George and Evil Harold attempt to use it to shrink Good George and Good Harold, but they are tricked into shrinking themselves instead. The Shrinky-Pig is used a final time to shrink Sulu back to normal size.
