In the first level of this game you can find a rocket car. Find the power plant and take the tunnel all the way through. When you arrive out you will see large mansions. Go straight out, turn right, then left and immediately to your left will be a gold house. Walk up to the front gate and you will see a rocket car from that old episode. Get inside with Y. Keep in mind that this car is extremely fast and not so durable so be careful.
