When you see the first ramp near the end of the stage, get your jump to maximum height without slowing down. Make sure you are going at maximum speed and hold the Analog-stick Up. If done correctly, you will hit three spider webs and cut off part of the track. Additionally, when you get to the part where you are about to go onto the centipede thing. To make the centipede get to the opening faster, before you go on the centipede shoot off to the right. The centipede should go down or up. Either one is good. The centipede should go to the left, then go to the hole faster. In White Cave, follow the steps above except go to the right.
