Tails' Story

One morning in the skylines of Station Square, hours removed from the attack from Chaos last night, Tails is testing out his new plane until it begins to malfunction and flies crazily over the city and then over the Station Square hotel.

Minutes later, Tails crashes in Emerald Coast. But to his fortune, Sonic arrives and extend his hand to his longtime friend. They return to the beach, and Tails reveals that the plane was powered by a Chaos Emerald and asks Sonic to meet him in his workshop in the Mystic Ruins to show him what he's been working on there.

Sonic and Tails are confronted by Dr. Eggman, who is assisted by Orbot and Cubot. He demands Tails to give him the Chaos Emerald. Tails refuses, so Eggman sends his Egg Hornet.

Boss: Egg Hornet

After the Egg Hornet is destroyed, Tails notes how defeating it was easy. Suddenly, Eggman steals the Chaos Emerald and feeds it to Chaos, who just arrives. As Eggman and Chaos disappear, Sonic and Tails decide to find the Chaos Emeralds before Eggman does.
