In a trailer for Monsters University, Sully plays a prank on his roommate Mike by gluing mirror shards on him and transforming him into a disco ball. Mike was not too fond of the joke, but he probably will appreciate his face on Epcot’s Spaceship Earth. To celebrate the new movie and summer vacation, Disney Parks will remain open for a full 24 hours.
