Disney/Pixar is making a lot of children equally scared and happy this summer -- they're releasing a prequel to Monsters, Inc.
Monsters University follows Mike and Sulley before they were incorporated, when they were just young adult monsters getting a degree in (what else?) scaring.
The studio released a trailer for the film Tuesday, and it seems like the movie has a bit of a plot twist. Mike and Sulley aren't the best buddies we've all grown to love (or be scared of). Back in their collegiate days, these two monsters were constantly competing to try to prove who was the best monster on campus.
If you thought your college days were wild, you haven't seen anything yet. The movie releases June 21, 2013.
