Disney movies loved Easter eggs. You can find hidden cameo appearences of characters from Disney's other movies, by means of posters in movie frames, few objects which symbolize the character and even complete not so hidden parts. As in, Aladin's Gene changing his face to Pinocchio in one of the many transformations he induces to himself. In that movie with the mouses flying by a tin tied to a bird, there are posters of characters from other movies. The set of porcelain from Beatuy and the Beast find themselves in Alice in wonderland, etc. The list goes on and on. On parks, you can find Mickey's head (the three circles) made out of a variety of things, I'm not familiar too much with the parks as I haven't visited it again ever since I was a kid. Hope this was a bit helpful.
you can find the bear from toy story 3 in up. in toy story 3 the dumpster man is the original kid who made the scary toys.
I am sure you have already gone, but I only know the old easter egg of yelling, "Andy's coming" to a Toy Story character and they fall down acting not real. They don't do it any more because everyone learned about it and characters were getting hurt. http://www.quora.com/Is-it-true-tha...ney-they-will-stop-what-theyre-doing-and-drop
