Jump up by the cowgirl, then jump up till you get on the train tracks. Run right and you should see a rope dangling down. Climb up and use the pea shooter to get the mine key from the fat canary. Use the mine key on the door with a lock on it, and then you'll be in the mine. You will ride the mine cart for a LONG time. Shoot the red switched to avoid falling off the cart. When you are at the end, grab the blue tulip. Then a tremor will happen. But there is a rope above you. Climb out.
