Miles "Tails" Prower, the fox, can't sit still when Sonic's around. Ever since Miles was a baby fox, he's dreamed of being like Sonic. He Loves to run after Sonic, waving his 2 tails behind him, trying to keep up with his hero!

Mostly, Sonic lets him trail along. But Sometimes, just to show off, Sonic explodes in a burst of super speed and leaves him behind. But Miles doesn't give up. He whirls his tails like a helicopter rotor and takes off flying until he catches up!

All the other animals call Miles by his nickname, "Tails," because of his 2 special tails. And one day they saw an astonishing feet...

They were all together in the forest, watching Sonic perform. Sonic would run, spin and jump in his Super Sonic Spin Attack. Then "Tails" would whirl like a turbo engine and blast off in his Super Dash Attack. What a showoff!

Suddenly, "Tails" just couldn't help himself. He took a running start, curled up his tails, and -- whoosh -- he was spining like Sonic!

But something frightening is happening. Sonic's friends are disappearing. In their places, nasty metal robots are poping up all over the island. The mad scientist Dr. Robotnik is at it again!

This time Robotnik is planning a global disaster. He needs workers to create a doomsday machine that he can take over the world. So he's trapping all the animals, turning them into robots, and forcing them to build his ultimate weapon, the Death Egg!

Robotnik now rules the factories, refineries and cities! He's grabbed control of everything -- except the 7 Chaos Emeralds. These magnificant gems are believed to hold exceptional powers. With them, Robotnik could have the entire world in his grasp. And he'd never let go!

The Chaos Emeralds are buried somewhere on the island. Only one tough dude with spiky hair has the speed to find them first!

Help Sonic stop the devious scheme of the demented scientist! Spin like a speedball through space. Grab Power Sneakers and loop 'til you're dizzy. Twirl over twisting speedways and rocket through tunnels. Balance and blast across a bubbling ocean of oil!

Find the Emeralds, free the animals, and squash Robotnik forever!
