When Tylor Tuskmon arrives at Monsters Incorporated to begin his dream job as a Scarer, he discovers that scaring is out and laughter is in. As a result he is temporarily reassigned to MIFT, the Monsters Incorporated Facilities Team.

When a human baby's room is damaged by a Jokester, Tylor has his first experience working with MIFT on the repairs. While the room is repaired, Mike and Sulley must take care of a human baby.

Tylor achieves his dream and is promoted to Jokester… but he feels torn on leaving MIFT. Meanwhile, Laugh Power is threatened when Mike and Sulley are given an ultimatum: generate more power or be shut down.

Johnny takes Tylor on a tour of FearCo. When Tylor is late returning from his visit, Val must cover for him by trying to make a kid laugh!

At the annual Monsters, Inc. vs. FearCo softball game, Val tries to tell Tylor about a job offer from Mike & Sulley, but Tylor is too busy considering his own future to listen.

Mike & Sulley lead a morale-boosting company retreat in the spooky sub-basement of Monsters, Inc.

When news anchors Jack & Jill visit Monsters, Inc. for an interview, Mike & Sulley hope to show off Laugh Power to all of Monstropolis.
