Things really stink in the Kingdom of Armpit. King Reginald the Not Very Realistic has had it up to here with his practical joker of a son Prince Harry. Even Sir Bedwetter can't take the prince's Royal Clowning Around! Enter Sir Fartsalot—the bravest, boldest, er, most potent knight in all the land! He's on a quest to solve the riddle of the Foul West Wind, a ghastly odor that turns up whenever danger is lurking. Prince Harry decides to play the biggest, boogeriest prank of all time! He convinces Sir Fartsalot that The Booger, a frightful and repulsive villain, is on the prowl. But when a real Booger turns up, Harry, Sir Fartsalot and the knight's old buddy Sir Knotaclew must set out on a hilarious quest to rid the world of the Snotty Scoundrel, once and for all!
