Captain Underpants

by Dav Pilkey 

With such titles as Captain Underpants the the Tyrannical Retaliation of the Turbo Toilet 2000, Captain Underpants and the Attack of the Talking Toilet, Captain Underpants and the Invasion of the Incredibly Naughty Lunch ladies from Outer Space and Captain Underpants and the Perilous Plot of Professor Poopy Pants, kids will laugh out loud with these colorful graphic novels. 

George Beard and Harold Hutchins turn their principal, Mr. Krupp, into the "greatest superhero of all time", The Amazing Captain Underpants. George Beard and Harold Hutchins are two mischievous fourth-graders who attend Jerome Horwitz Elementary School in Piqua, Ohio. They are known for making comic books featuring Captain Underpants, a superhero of their own creation. After the boys ruin the school's football game with practical jokes, their principal, Mr. Krupp, threatens to expose their mischief to the football team using video evidence unless they submit to a list of rules he gives them. George and Harold find themselves on their best behavior, doing extra homework, and chores for Krupp

.To escape their punishment, George orders a "3-D Hypno-Ring" from the Li'l Wiseguy Novelty Company. The boys use the ring to hypnotize Krupp. 

This is all very believable to this age group. My grandkids loved the illustrations of a principal in his underwear on crazy adventures.
