The 25 Years of Sonic the Hedgehog

Sonic Shuffle (2000)

The story involves Sonic, Tails, Knuckles, and Amy getting caught up in a mess in a world called Maginaryworld, which they inadvertently stumble upon one day when Lumina sends a vortex to take them inside the dream world. A villain named Void has shattered the Perfect Precioustone into many pieces, resulting in chaos in every part of the world. Lumina Flowlight and the rest of Maginaryworld are counting on Sonic to restore it and bring Lumina back, who mysteriously disappeared along with the Perfect Precioustone.

The game progresses in multiple story lines and playing as each different character will allow the mystery of Void to finally be realized. After each world is successfully restored the chosen character will confront Void with Lumina. As they interrogate him the chosen character is able to finally realize the true meaning of what Void is trying to say. Each character has a different story and will realize that Void is the emptiness that allows dreams to be created in the first place.

The group makes their way to the Nature Zone, a jungle created from dreams of those wishing to be one with nature. However, Void has placed dark pillars in the jungle. After acquiring the six pieces of the Precioustone, the group is given a set of keys to unlock the last Precioustone. When the four obtain the final piece of the Precioustone, an earthquake occurs and they are forced to escape. The jungle is restored to its original state, much to the group's surprise. Sonic, Amy, Tails, Knuckles and Lumina then enter the Riot Train, made from a dream of those who love adventures. However, the train is unstable. After collecting the pieces of the fourth Precioustone, Sonic, Knuckles, Amy and Tails successfully push the train to a stop.
