With the help of her horrible robots and her horrendous hairdo, Wedgie Woman is on a mission to take over the world, and she'll give a whopping wedgie to anyone who stands in her way--including Captain Underpants. Will Wedgie Woman's wicked ways spell the end for our heroes? You'll have to read the book to find out. And in the meantime...watch your back!
