If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
The moving van is leaving Buzz and Woody behind and only you can help! Slink is hanging out of the back of the truck, so all you have to do is take the controls of RC and drive as fast as you can to reach him. Watch out for the other cars on the road and avoid all hazards along the way, and you'll be home free!
