Nick's New Mario World: Star World 2 Secret Exit

The secret exit to Star World 2. The big difference is that you have to do some bouncing off a flashing Koopa shell and you have to guide it across the field of muncher plants by moving forward after bouncing on the shell. You also need to have the key in your possession and you will be hopping over some inconveniently placed muncher plants. This exit is also the only way to get the final two Yoshi Coins. No savestates used.
