Can’t think of any more unique Disney costume ideas? Here’s one – how about Sulley from Disney/Pixar’s Monsters Inc? James P. Sullivan, that’s his full name. He’s the friendly and caring blue monster that sort of looks like a huge feline/dragon who can stand on two feet. He’s best friends with the one-eye green monster Mike Wazowski. He’s also the monster who bonds with Boo, the human child who came into the Monster world. Boo’s the one who nicknamed Sulley as Kitty. Getting back to the Sulley Disney costume, you’d need a body suit that is furry and has a few purple polka dots here and there. The head piece needs to have thorns, and you’d need claws for hands. Good luck!
