dont know if anyone has commented on this before,but happened to notice last night ,in the scene near the end where boo gets returned to her room,nemo or his dad is one of the toys boo hands to sully perhaps there is a wee clue in nemo to the next pixar film
They talk about this in the commentry or one of the "Making of" docs!
Jessy the cowgirl is also one of Boo's toys plus Boo gives Sully A ball wich was in Pixars first animated cartoon. Theres lots of little references in Boo's bedroom to other Pixars works. Look closley and you will find them.
