Mr. Marvelous (Mr. Men and Little Miss)

Mr. Marvelous can out-tickle Mr. Tickle, outrun Mr. Rush, and out-chatter Little Miss Chatterbox. He is simply a marvel! But when he tries to out-naught Little Miss Naughty, he finds that there's nothing marvelous about playing tricks on people. Will he lose himself in a prank fight, or learn to embrace his naturally marvelous personality?
