Secret Easy Passage Way To The Mad Doctors Lab.
After arriving to your new destination from Disney Gulch, You may see the junk bridge. If you want you can take the junk bridge to obtain more items, but this is just an alternate passage way. The first thing I would do is defeat the car blotling. After you defeat it stand in the spot you started at next to the train. If you look around you there is a thing with red-ish, green, and light blue wires on it. Thin it. Afterwards jump on the platform that's there, paint the other platforms, and get one of the special pieces of art that you can get in the game. After you get that follow the broken railroad track until the very end. Look around until you see another thing with wires and repeat the steps you did with the other side. Once you reach the end of the platforms there is a thing that you need Oswald's Electric stream for. When you get finished it should send and Electrical current to what looks like a Lizard. It's mouth should open revealing a pin and a projector screen to the Mad Doctor's lab.
