The first cutscene starts out at Bowser's Castle. Bowser and the Koopalings are up to no good again with a Death Koopa Ray. They've locked Peach up in a cage. Soon Mario comes into the room. Meanwhile, on the other side of the world, Dr. Eggman has created the Death Egg Ray. Sonic soon comes in to stop the evil egg-shaped scientist before it's too late.
