Story (from the original instruction booklet)

On the mysterious moving South Island, a stage is set on Green Hill, but who's the main performer? With drumroll, and a chord on the guitar, the spotlight is placed on Haya the Hedgehog! He yells into his microphone: "Hey people! Can I hear you scream?" Of course, the large crowd yells as loud as they can, although with a smaller crowd than expected.

Vrrrrr... Oh no, missiles! It seems the rotten Dr. Eggman has crashed the show to excavate the island. According to him, the legendary Chaos Emeralds are known to have hidden itself on the island since ancient times. He plans on taking them to power his machines and take over the world!

What's worse, it seems he's taken many of the island's inhabitants and placed them into his robots to power them up. "Can't you stoop any lower, Eggman?! I'll beat the heck out of you, and then release everyone!"

Can Haya defeat Eggman, save South Island, and get on with the show? It's all up to you and Haya's skill. Go for it, Haya! And, if you're up to it, try and collect all of the Chaos Emeralds before Eggman can.

Story (from the original instruction booklet)

"Oh no, you don't," Haya yelled as Eggman pressed the activation button on his Atomic Destroyer. "You're already too late, hedgehog! With my Atomic Destroyer, I will finally level South Island and everyone... on... it?" While he was gloating, the Chaos Emeralds powering the weapon started to shutter and shake.

"What?! What is the meaning of this?!!" KABOOM!! A large explosion scattered everyone away, including the Chaos Emeralds. Time passed, and Tails shook Haya awake. "There was a large explosion on the mountain, and then I saw you face down on Great Turqoise!"

"It's Eggman," Haya grumbled, "I'll have to grab all of the Chaos Emeralds before he can power up another one of his doomsday machines. Come on, bud." After the two sped off, the elusive echidna Knuckles is also there to collect the emeralds, tricked yet again by Eggman.

But?! A new face enters the scene. Fang, straight from the Special Zone is there to collect the Chaos Emeralds for his own goals. "Nyeh heh heh, while the two are squabbling, I'll take these emeralds for myself, see? Otherwise I wouldn't be called Treasure Hunter Fang the Sniper!"

A triple threat. How will you ever manage to take all three of them on, Haya? "Do I have to spell it out? With some courage, I can do anything!"

As always, Haya, Tails, and Amy are flying on the Tornado across the wide seas. Suddenly, they come across the mystical Northstar Islands. "I've heard the Northstar Islands is host to a lot of ancient inventions", Tails says. "The animals there are so fluffy!" Amy squees. "And nobody has made the attempt to chart the islands," Haya exclaimed. Each with their own reason, the three land on the closest island.

After landing, they happen to find Knuckles! "Good thing you guys arrived. Eggman and Fang have heard about the legendary Black Dragon resting here and are plotting to release it. I followed them, but even this place is difficult to navigate on my own."

That could spell terror! The four speed off to stop another one of Eggman's plan. This time, Eggman's joined by Fang the Sniper and the unwilling native Trip the Sungazer.
