The third book in Dav Pilkey's mega-bestselling Captain Underpants series, now available in Sound-O-Rama! George and Harold have played a trick or two on nearly everyone at Jerome Horwitz Elementary. When their latest prank causes the school’s cranky cafeteria ladies to quit, Mr. Krupp hires a trio of unusual replacements — who happen to look an awful lot like aliens! Will that curtain-caped crusader, Captain Underpants, save the day once more? Or will those outer space cafeteria ladies have him for lunch? The Captain Underpants series is perfect for listeners of all ages. Like the other outrageously funny books by acclaimed author and Caldecott Honor illustrator Dav Pilkey, this adventure is sure to be hours of fun!
