Plot
Sonic and friends search everywhere for the last missing chaos emerald. Chris is a little bit torn because he wants his friends to be able to go home to their world, but at the same time, he will miss them. Mr. Stewart convinces Chris that letting them go is what is best. Dr. Eggman in the mean time has deployed Lucky to go out and find the 7th chaos emerald.

Knuckles walks through Forrest Hill, talking to himself, worried about the Master Emerald. He concludes that it is up to him to reconcile the differences between Sonic and Eggman in order to get all the emeralds together and return home. Knuckles finds the Egg Fort II hiding in Forrest Hill and he also finds Lucky who follows him to Chris' house. Chris and Knuckles go to the Egg Fort II and make a deal with Eggman to combine collections of emeralds. Eggman tricks them into trusting him.

Chris takes the 4 chaos Emeralds that Sonic and his friends collected and he and Knuckles take them to Eggman. Meanwhile Lucky has fallen in a dumpster and ends up wandering the South Weast Dump where he finds a box containing the seventh chaos emerald. Lucky call Eggman on the phone and informs him of the good news. When Eggman hears that Lucky has the seventh emerald he betrays Knuckles by activating a trap door underneath him. Eggman then tells Chris that he does not care about staying there or going home, he just wants to establish his Eggman empire.

Sonic arrives in Forrest Hill in time to find Knuckles on the ground and the Egg Fort II taking off. Knuckles tells Sonic that Chris is on board, so Sonic chases after the ship.
