Captain Underpants and the wrath of the wicked wedgie woman / Pilkey, Dav

George and Harold are always good at using their imaginations, and that drives their mean homeroom teacher, Ms. Ribble, crazy! But this time, they've come up with much more than a silly prank -- they've accidentally created a MONSTER! With her horrendous hairdo and two rabid robots, Wedgie Woman is well on her way to world domination, and only the Waistband Warrior can stop her!.

Using their 3-D Hypno Ring on Ms. Ribble, George and Harold create a monster that will give a whopping wedgie to anyone who stands in her way--including Captain Underpants.
