don't click until when you get to the bottom of the screen in world 1-2 don't press space until you click the green flag and get to the top of the screen. remember in world 1-2 make sure you spin to look like your defending your self from the black spikes,and when you touch the spikes jump to look like scratchio is hurt, and the ? block in 1-3 is a 1-up block ;) and touch the spikes to much and you will have to put scratchio at the bottom of the 1-2 screen.
