If you're a fan of the "comics" seen in the Captain Underpants series, chances are you'll love this. The entire series is in comic format, as if this entire book is actually a graphic novel written by George and Harold. As can be expected, the humor is a bit more disgusting than the average Captain Underpants book, with more potty humor than you can shake a stick at. Still, if you can get past the gross parts, you have a laugh out loud funny story full of charm and wit.
