Chapter 13: Launch Base Zone

Sonic and Tails are riding on a 'borrowed' Egg Mobile. "Ha! Thought you could stop me from protecting my Master Emerald," said Knuckles, punches their mobile. But when the launch starts, Knuckles falls off. "I got all of the Chaos Emeralds, so what's the Master Emerald," said Sonic. "The one thing to power up my Death Egg," said Eggman, prepare to attack with his Beam Rocket. "I bet by a 100 Gold Rings that you were the one who lied to Knuckles that we're trying to the Chaos Emeralds," said Tails, as they battle. "I got you covered, buddy," said Sonic.

Once they defeat Eggman, Eggman fled and the Rocket falls apart. Sonic and Tails watch the Death Egg fall. "Tails! Get us out of here," said Sonic. "You got it," said Tails, lifts Sonic as they land safely. They find themselves on Mushroom Hill Zone. Then Sonic found Knuckles locking a door with a button. "Smells like Knuckles has a little secret of his own," said Sonic, as he and Tails enter the hidden place.
