Plot
We see Big and his pal Froggy sleeping when something falling from the sky wakes them up. Froggy hops over to the spot and sees a Chaos Emerald. Big follows and sees the Emerald as well. Then some strange blue liquid comes up behind Froggy and he swallows it. Big asks if his pal is okay and sees that Froggy has somehow grown a tail. Then he swallows the Chaos Emerald Big picked up and hops away with Big in pursuit.

Meanwhile on the President's plane, he remembers what happened six months ago when Chaos Control erupted and a piece of Sonic's world entered this world. He and the people he has with him on board are planning to boost the economy by turning Mystic Ruins into a tourist attraction. The President then mentions that he's still worried that Dr. Eggman may strike any time soon, but one man says that he's got intelligence teams trying to find him. Rouge suggests that he may be taking a break to plan his next move. The President then asks Mr. Stewart how Sonic and the others are doing. He shows him some photos that they are doing okay.

At Chris' house, he, Chuck, Cream, and Cheese are busy having breakfast. Chuck asks if Chris could go with him to Mystic Ruin where Tails has set up a workshop, but Chris declines the offer as Linsey has something to show him, Cream, and Cheese after school. After leaving the house, Chris looks up at the sky and thinks to himself, "I know you're out there, Sonic. I sure hope you're okay." Meanwhile in Windy Valley, we see that Sonic is okay.

Elsewhere in Station Square, Amy has moved to an apartment building and thinks of the times she spent with Sonic and how much she misses him. On her small TV set, Scarlet Garcia mentions that the whereabouts of Eggman is still unknown. But we see him in his new fortress making a new line of robots: the E-100 Series, consisting of E-101 Beta, E-102 Gamma, E-103 Delta, and E-104 Epsilon. Then he says it's time to create chaos, walks over to a Chaos Emerald, and launches his new flying fortress, the Egg Carrier.

Meanwhile, Linsey shows Chris, Cream, and Cheese a Chaos Emerald she got from a jewelry store. She gives it to Cream as it does not match any of her outfits. Later the three of them are walking down the street when Cheese gets mixed up with Froggy. Later, Big accidentaly piles on top of all of them and Froggy hops away again. Big tries to explain to Chris and Cream what was going on which takes all afternoon. They both offer to help look for Froggy which takes them into the night. After many hours of searching, they find something, but it's not Froggy, it's some of the strange liquid that Froggy swallowed. It reforms to show a creature. Then it starts destroying everything in sight, scaring the people away. Chris, Cream, and Big start running away while it's not looking. Elsewhere, Sonic catches sight of the commotion and steps in to help stop it. Chris is happy to see Sonic again. Sonic begins to fight the creature and easily defeats it. Then Eggman shows up and takes Cream's Chaos Emerald and feeds it to the creature whom he calls Chaos.

When Chaos 1 is about to attack, an angry Knuckles shows up asking Eggman about the Master Emerald which also made its way into the Chaos Control. Eggman then gives Chaos 1 another Chaos Emerald transforming him into Chaos 2. Sonic and Knuckles try their hardest to fight Chaos 2, and with luck they manage to defeat it. Afterwards, Eggman sucks up Chaos 2 into his Egg Pod and flies away. Sonic and his friends are positive that Eggman will be back, as well as the Chaos creature.
