Captain Underpants and the Invasion of the Incredibly Naughty Cafeteria Ladies From Outer Space is the third Captain Underpants book by Dav Pilkey. In this book, George and Harold play a prank on the lunch ladies that makes them angry and causes them to quit. Three aliens then dress up as human women and get hired as their replacements. They feed all the kids evil zombie juice, turning them into zombies that they will help them to take over the world. Will George, Harold and Captain Underpants be able to save the day, or will Earth now be ruled by the aliens and their zombie minions?
This book is very humorous, and Dav Pilkey does a great job of managing to make nearly everything funny, from the prank on the lunch ladies to the kids and Captain Underpants nearly dying. However, although it was a fantasy book, at one point in the book, something completely unlikely happens, which the book even admits is impossible. Because of all this, I give this book a four out of five.
