Captain Underpants and the Preposterous Plight of the Purple Potty People

[1] It was published on August 15, 2006, two years and eleven months after the release of the previous book.

For example, Melvin Sneedly is dimwitted and struggling to comprehend a simple children's book (which contains content considered offensive in the normal universe), the teachers are nice, the school is better, all the previous villains are good, normal citizens, and Mr. Krupp is nice and has a sense of humor.

Sulu immediately attacks, but Crackers saves them (due to secretly being female).

George, Harold, and Crackers are able to escape to their normal dimension and head to the treehouse, unaware that Nice Mr. Krupp, Sulu, Evil George and Evil Harold came with them (due to standing too close to the machine).

Meanwhile, George and Harold decide to head back to the other dimension to rescue and de-hypnotize Sulu and take the 3D Hypno-Ring and Extra Strength Super Power Juice just in case.

With only one plan left they turn Mr. Krupp into Captain Underpants, who defeats Sulu.

Suddenly, a robotic pair of pants appears, piloted by Tippy Tinkletrousers.
