James P. Sullivan is one of the friendliest monsters you will ever meet. Dress up like the Monsters, Inc. protagonist in our Deluxe Men's Monsters Inc. Sully Costume. It comes with a plush blue top with light blue belly purple spots and a detachable tail, a blue fuzzy head piece with gray horns, and a detachable beard. Sully has a reputation as Monster's, Inc. number one scarer, but after his adventures with Boo who he accidentally let's slip into scare land, he realizes that it is much better to power the town with laughter than with screams. He revolutionizes the company and replaces corrupt Mr. Waternoose as the CEO. Dress up as Sully and have your best friend dress as Mike Wazowski for a fun costume party idea.
