I am going to talk about the ending!
Do not read unless you want to know!
Toy Story 3 is about the adventures of Andy's toys when his mom decides to throw them away because she mistook the bag for a garbage bag. Woody and the toys climb out of the trash and into a box of donations for a day care. The toys escape and find their way home. In the process, Buzz gets a concussion.
At the end, Andy finds a note on his box of toys that is going to the attic to be donated. He thinks the note is from his mom, but it is really from Woody. So, he donates them to a little girl who is really good with toys. Only he doesn't know Woody is in the bottom of the box. The little girl keeps Woody and she calls him her cowboy. Andy played with the little girls with all of his toys again before driving away and going to college.
I really want this movie and the first two!
