It's easy, just continue where I left off and insert your characters in place of mine. They can be frozen by a pulse.

So here's the plot: Durring Sonic's last battle, Eggman used a device to neutralize the Chaos Emeralds, by doing this he released the negativity in the form of a black creature. In the battle, Cream lost Cheese, and giving into lonliness, asked the black creature to create a replica of Cheese using the released positive energy of the Emeralds. Although "cheese' was with her, Cream was still lonely. The evil creature also wanted to feed it's need for Chaos, so it asked Cream if she wanted to play forever. She said yes, and he released the Obelisks from his own flesh, devouring the Chaos and giving cream hundreds of crystal dolls to play with.

Yeah, pretty dark. You guys stop him 1) going to the World well under the Master Emerald, 2) putting Alice in there to be revived and 3) she uses her powers to recharge the Emeralds and suck the creature back in, for he can only exist when the emeralds are inert.
