Possibly. Although they have appeared together in various titles, they don't appear together in a main series game-only in spin-offs. The only exception to this is in Sonic Adventure, where, in the NiGHTS pinball table, the character appears. But he has no reaction that differs from the on that Tails gets when playing the level. Even then, it could just be a model, built into the casino. In the spin-offs, they will probably know each other.

I haven't heard of Amy Adams, but I know of sonic the hedgehog, so I think sonic is more famous.
We all know that Jaden Smith is a cool actor but, unfortunatly Sonic is known more. 3/8 of Americans know Sonic while 1/8 know Jaden. :(
Yellow Hedgehog? Well, you know there is a white hedgehog and that he's Sliver the Hedgehog! Unfortunately, he is sliver in color. Sorry. Also that you must be mistaken with Super Sonic as in the Yellow Hedgehog but that's only in his super transformation. So most likely, there is no Sonic character that, I know of, is a Yellow Hedgehog. Accept my apologies, senior.
