User blog comment:David Bear/Sonic's home world is in fact Mobius, not Earth/@comment-27035837-20130419234850

I don't usually respond for the other's blogs, but I want to clear this case here: the first part of the 3DS description that David Bear sends to Myself as respond is actually from american instruction manual of the game:

"While the evil genius Dr. Robotnik is testing the ultimate destructive weapon, one of his assistants makes a mistake causing his lab to explode and sactter the five Chaos Emeralds across the planet Mobius."

Here's the page from instruction manual of the original Game Gear game:
