The longer way to do this is to beat Chaos 6 is Sonic's story, or finish Sand Hill as Tails.

Alternatively, if you talk to Big in the Adventure Field, you unlock him then also. The soonest you see him is right after you finish Ice Cap and right before you start Twinkle Park. You can find him in Station Square, in the area with the elevator to Twinkle Park. He'll be standing to the right of the dock. The achievement won't pop until you exit the game and go to the character select screen, and you'll get it the moment you do.

Happy hunting!
