Change can be tough. And if humans have a hard time dealing with change, just imagine how terrifying it must be for toys. Inanimate objects have no control over their own lives. They don't know when they're about to be played with, thrown in a trashcan, lost, or sold at a garage sale.
Woody and the other toys in Toy Story deal with coming change in the best way they know how—by freaking out. Gradually, they learn that not all changes are bad. Some can even bring cool new roommates.
