Rainbow, Zipp and Sonic's Racing Adventure

-At Luigi Circuit-

A strange human-like cat from another universe named Karen stands at the food cart, waiting for any customers to came by... with a sigh. As just as her hopes finally given up, the three racers teleported out of nowhere and stops at a food cart for a quick snack break.

"Ah, Sonic!" Karen said, "Having fun with Swag I see?"

"Wait, who's Swag?" Sonic said in confusion.

"Oh wait, you're the movie version." she realized. "Anyway, what would you like to eat?"

"I'll have a chilli dog" Sonic declared.

"And i'll just have a soda." Rainbow said as she got her hoof to the cart. "Hey, Zipp! You want anything?"

"Nah, I'm fine." Zipp said.

After Sonic payed for the food, they started to dig in. But as they do, one of Eggman's Egg Chaser flew by to spy on them from behind.

-In the Egg Carrier-

The Big Man, Dr. Eggman himself was using his computer to watch the three racers dig in in the Egg Chaser's Camera System. He was so surprised to see another version of Sonic. But with the new 3rd Sonic Movie coming this December, he'll take an advantage to cover his movie counterpart, Robotnik and make sure he'll be avenged. Suddenly, Metal Sonic camed to his master and about to tell him something.

"Master." He said.

"What is it?"

"I came to inform you that there's a different version of Sonic in our mist." Metal Sonic explained.

"Really?" Eggman said.

"Yes, really." He continued, "And he's with the ones who called, Rainbow Dash and Zipp Storm."

"You mean, those two ponies from a different dimension? I heard." Eggman said as he pound his left fist to the table in anger, "They might be taking a break by now."

"What should we do now?" He asked.

Finally, Eggman turned to his creation and answered, "Get all my robots to go to this location and wait for me there, it's time to take down Sonic and his new pals. Hahahahaha!"
