Sonic and MLP two worlds collide

That sounded like Tails!

That scream didn't come from the roof.It came from high in the clouds."That is somewhere in Cloudsdale which is where Rainbow Dash and Scootaloo live."Sonic said.Shadow Chaos Controlled everyone/pony to Cloudsdale to save Tails and get him out of Cloudsdale.They went searching for Tails and no-one found him anywhere.The only place they haven't checked yet was Rainbow Dashes home.So they all went to her home and went to see if Tails was there and help him out.They entered her house and saw Tails injured and already helped out while he was asleep."Tails are you okay?"Sonic asked."I'm fine Sonic.I just feel surprised that I've been taken care of and that I'm on a cloud."Then Rainbow Dash gets back to her house realizing that Sonic and friends are in her house."Except for Tails,what are the rest of you guys doing in my house?"Rainbow Dash asks."We were here to look for Tails because he went missing."Amy said."This isn't a joke is it because I don't like when ponys or people like you play jokes on me?"Rainbow Dash wondered."No it isn't.Now why would you think it's a joke?"Shadow said.After Shadow takes a step closer to Rainbow Dash she grabs Shadow and throws him to the floor and throws him straight out the window."Now I know to not fight with Rainbow Dash."Sonic said.Rainbow Dash saw the emerald on the ground glowing."Hey what's that?"Rainbow Dash asked."Oh that's called a Chaos Emerald.It's very special to us and still are trying to find the rest."Sonic explained."Mabye I can help you find those Emeralds.After all,I'm the fastest flying pony to ever come out of Cloudsdale."Rainbow Dash proclaimed."Sure thing."Sonic said.So Sonic and friends including Rainbow Dash went off to find the rest of the Emeralds to get back to Mobius.All they needed to do first is to get Knuckles because he was the greatest treasure hunter and he is the only one who knows where the rest are.
