What if humans discovered that toys have their own life and not only that they are smart with ability to speak like them. Surely something terrible would happen, that is why Toy Story toys must remain motionless when approached even if intended to destroy.
This will make Woody the sheriff and Buzz Lightyear , the interstellar guardian join forces to rescue lost or abandoned toys. This will lead them to live a thousand adventures in which our human world will seem as big as a skyscraper us.
Use your wits to overcome stairs, open a window or any other obstacle that stands between you and your goal. But all is adventure as toys can relax riding a good party with the best music that Rex is the soul of the party.
When a change occurs, it is also necessary that toys care of each other because if anyone is lost can not rescue again.
