Toy Story 3 Easter Egg - Sunnyside Daycare Eggs

Characters from other Pixar films are scattered among the children at Sunnyside Daycare. Among them:

Mr. Ray the Scientific Stingray from Finding Nemo
A wooden homage to Lightning McQueen from Cars.
The number 95 appears on a kid's shirt and on the train. That's Lightning McQueen's number and also the year the original Toy Story first screened.
Drawings on the wall contain some Finding Nemo characters.
Among the tiles on the short wall outside is a drawing of a Luxo Jr. ball.
Several references to Tin Toy are strewn about, including a group of toys is hiding and shivering in a corner, like they were under the couch in Tin Toy.
