In the opening credits is a drawing of an open closet. There
is a toy truck in the closet. On the side of the truck is what
looks like a stylized Mouseketeer hat. This shot is repeated
later (closing credits, I think).

Where it is showing the the overhead view of the town scene, where Mike and Sulley are going to work
there are 3 buildings that make a Mickey head!

Early in the movie, while Sully is working out, there is a poster
behind him (NOT the "Jazz" poster). In one shot it looks like
there might be a three-circle Mickey in the poster.

At the beginning when the monster is in the training simulator, there are three monsters watching and taking notes. The yellow one on the far left has three eyes that really look like that famous Disney mouse. Even though it is at a side-view you can clearly see the three distinct circles.

In the begining of the movie, the snake monster is going through all the doors it goes through a door that has a bunch of toys on the ground and one of them is a toy truck. On the side of the toy truck is a Mickey head.

There is a child's drawing of Mickey Mouse on the drawing board in Boo's bedroom. Can best be seen toward the end of the movie when Sullivan is returning Boo to her room.
