You think to yourself "Huh? What's going on right there?"

*You decide to go there quickly as possible...you were walking in a place, you stomp on something IT WAS A DEAD ANIMALS!!!! You think to yourself "D...DEAD ANIMALS?! WHO'VE COULD DONE THIS?!" suddenly you saw someone...it was sonic? Or not The figure that looks like sonic noticed you and smile Evily

"Aaah! Looks like you found me... I've gonna say you entered to this dark place without fear... how impressive!"

You look at him in angry way and you say "who are you? why are you here? And what do you want?!"

The figure laugh "Oh who am I? I'm core, I'm here to take all over this place called..MOBIUS" "And what's your name, little plaything"

You introduced yourself and the figure come near to you, checking you closely

"Hmmm..{{user}}? What an interesting name you've got"
