The beginning for a young boy, in which a surprising enterprise he had found just from the common fear of the old closet monster, was as elaborate as it could be. Where humans live their day to day, bustling lives, there existed another cosmos of creatures and beasts whose sole purpose is to extract the scream energy from terrified, sleeping human kids. For one lucky boy and a faction of monster's , it all unraveled and produced for them. All it took was some courage to stay awake and find out, and the monsters to lower the wall of suspicion built on lies.

Y/N, Mike, and Sulley have all been accepted into Monsters University. Even though Mike and Sulley don't become friends immediately, Y/N and Sulley are hitting it off here and there. And the fun part of it all, Y/N and Mike have been best friends since they were kids (like a brother/sister relationship), so Y/N is always in the middle of their arguments. Then when all of them are kicked out of the Scaring Program, they are on the same team "Oozma Kappa" to try to get back in. Will it work?

Tylor is recruited by Monsters Inc. to be a Scarer, but when he gets there, he finds out they aren't scaring anymore, but making kids laugh. He is then brought into MIFT, a group in Monsters Inc. that repair parts of the company. Along with that, he is reunited with an old friend of his, Jamie, and they both plan to become Jokesters. Meanwhile, Sulley, Y/N, and Mike are put in charge of Monsters Inc and must make it run properly. Will they all succeed?

It's been eleven years since Y/N, Sulley, and Mike left MU and they have become the best Scare Team and Monsters Inc. Their main competition is G/E/N and Randall, who are in second place. Being the top Scarers isn't the only that have been going on for Y/N and Sulley! (You'll see as you read.) Then one night, a little human girl came to the monster world and Sulley, Y/N, and Mike were put into the mix. Will they figure out what to do with her?
