Spoiler - as opposed to the cover, he actually becomes a giant chicken nugget. Really. It's not a costume. The costume comes earlier.
It's wild and wacky and a bit gross, with ninjas and over the top bullies (the principal hands out months of detention on his son's demands because otherwise his wife will yell at him).
The black and white illustrations are just as kooky as the text, with both comic panels and illustrations inset. They show the characters making witty and silly statements and some additional action scenes.
Verdict: This wasn't one I personally got (although the ninja scene was very funny), but I can see it being very popular with younger kids who are fans of Captain Underpants. Parents will probably appreciate that it has the same wacky humor and illustrations but is much lighter on the potty humor.
