You may not know this, but there is a brilliant movie-tie in game on the PlayStation (1) called Toy Story 2: Buzz Lightyear to the Rescue. You had to travel through all the set's, Andys House, Als Toy Barn, The Airport, Allies and Gullies, and even the luggage bay of a plane, trying to save Woody, Jess and that horse that nobody can remember the name of. On the way, you must collect Pizza Planet Tokens so you can advance to the next level. To access Big Bosses, you must collect a certain amount of Pizza Plante Tokens, by doing one or more of the five activities found in each level; collecting 50 coins for ham, find 5 somethings for someone, beating a mini boss, doing a time trial, or finding a Mystery Token somewhere.
Unfortunately, this game never reached a Nintendo console. But with ToyStory3 coming up, they can have another chance. You could adventure through whatever ToyStory3 is about, then, if you've collected enough Pizza Planet Tokens/Beat the Final Boss(es), you could unlock ToyStory2: Buzz Lightyear to th Rescue.
Nintendo, if you're somehow reading this, make it happen!


This Screenshot is of the Elevator Shafts level. It is very tricky. going up here is how you get to Ham, and also how you find one of Mr.Potato Heads various body parts.


The first mini boss, you'll find him in the attic of Andys House. Lasers won't affect him, so spin attack him till he bends down lifelessly. Then laser him. Repeat until he blows up. Later, you'll meat his cousin, a robot-dragon in Al Toy Barn.
