George and Harold have really done it this time, they've created a MONSTER! She's faster, stronger, and smarter than anything the world has seen before. She's Wedgie Woman! 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 wrath spell the end for our heroes?
