Yeah, strangers staring wouldn't faze Goku in the least bit. So when the pretty blond lady approached him, Goku gave her a glance and a friendly wave but he did march right up to her and held out his hand as a greeting. "Hi, there! I'm Goku! Sure, I don't mind talking! What's up?"
His dark hair stood up all over the place, hair that had never changed since the day he'd been a kid. Five years old and everything with all that big hair that he has now. He'd certainly never seen this part of the world in all his crazy adventures, but Goku wasn't one to stop exploring here just because it was completely new.
