I have noticed there are 2 Subspace Emissarys!!!!
Remember the scene that you must fight vs Petey Pirahna to save Peach and Zelda?????
It depend of that, so if you broke zelda's cage, do a 2nd file and break Peach's cage. Now I will explaneit:
When you break any of the cages of the princess', the princess in the cage that you broke falls with kirby while the other princess falls far away from kirby, and Wario kidnaps her.
There will be the some little changes, with different videos, etc.
You can't really beat the Subspace Emissary with out doing this.
