The funny Mike (Mike Wazowski) is already known from Monsters, Inc. He and his friend Sulley (James P. Sullivan) make a super team there. Monsters, Inc. generates energy for the city of Monstropolis from the screams of frightened children. Before Mike and Sulley became real master scarers, they both attended Monster University. When Mike arrives at the university, a dream he has had since childhood comes true. His new roommate turns out to be none other than Sulley. However, it takes some time for the two to become true friends, as they first need to learn to get along.
