If Part 1 of The Big Bad Battle of the Bionic Booger Boy was the grossest book in the series, this one is by far the most ridiculous. It’s got everything from time travel and body switching to a catchy dance craze. And it’s great.

Very funny and silly just like the other Captain Underpants books. It ties up the plot from Part 1 nicely while also setting up the next book.
