Imaginary Fiends

Since the day he was imagined, Mr. Thrumpkin and Harry were the best of friends, but now, Mr. Thrumpkin could only watch as Harry slowly slipped away. Mr. Thrumpkin does what all imaginary friends do when they're no longer needed. He goes to the streets... to the back alleys... to the place where imaginary friends become imaginary fiends. Does Mr. Thrumpkin have what it takes to be an Imaginary Fiend, or will he remember his vow to be a forever friend and not a fiend?
