I have found a secert when you drive in the gb car with ray. What you do is play the level where you are in the car, but here is the trick dont go in the gb car. as soon as it starts go backwards then move right. You will then be able to rome ny on foot. Got to where the aprking is. If you go trough the sign that say exit and it blows up you are on the right track. Type in goggles so light will come on. Then type in slimer. Walk through every wall. go up down side side in all the walls evntually you will end up on a road.keeping the slimer mode on walk into the car. inside is a ton of proton packs and in the front seat is ray. and there wil be moving traffic. I did this all by accident but its there i sware.
