CAPTAIN UNDERPANTS returns for a twelfth adventure in this highly
illustrated comic book style series!
George and Harold, and their doubles, Yesterday George and Yesterday
Harold, have a good thing going. Two of them go to school, while
the other two hide in the tree house and play video games all
day -- then they switch! But when their malicious gym teacher, Mr.
Meaner, creates a method of mind-control that turns their fellow
students into attentive, obedient, perfect children, the future
of all humanity will be in George and Harold's hands!

This is Book 12 in the Captain Underpants Series. See all Captain Underpants books here.
