Maybe the most jaw-dropping of the titles in the series so far, this book ties the events of the previous 10 books into one action-packed, non-stop, thrill-ride.

A recap brings readers up to date with the plot thus far and then dives into George and Harold's near separation when Mr. Krupp finally devises the perfect plan to split the duo up. He decides to alter the way grades are gathered and fiendishly plots to fail one of the friends while sending the other on to fifth grade.

Not be outsmarted, George and Harold mess around with a time machine to foil Mr. Krupp's plan which allows for a duo of Yesterday George and Harold to add chaos and confusion to the story.

There's a lot to keep track of here plot-wise (especially with the old villains and their vengeance quests) and there's tons of butt-shots (hence the jaw-dropping). In Pilkey's world all adults have weird secret desires in their dreams...

Recommended for grades 4-8.

This was fun! The naked school teachers were a bit much, ngl but the baby hamsterdactyls were awesome!

Hehe other then "rude"-est humor ever in a children's book, that would be the first time I ever seen crude children's drawings to censor out the potentially traumatizing bits hehee.
