Psycho Fox Cheats

On world 1-3 where there are a few springs going up to the top of the screen. Go to the top of these and whilst still on the top one through your bird fly. After a few times of this a hole will appear. Enter this hole and you will go to a level with no baddies and to ways to go. If you take the route down, go through the first "pipe" and you will be transported to world 5-1.
