If he's still into that Toro game, he might accept your friend request, since the whole goal of the game is to get a bunch of friends.
Friend requests sent from the Toro game look exactly like any regular friend request, so he couldn't know if you found him through the game or not. Until he realizes that you're not on his Toro garden.
Heh, y'know, the funny thing about that toro game is that Chris extorted some of his PSN friends to get friends on the toro game. He told someone who's been on his friends list for awhile (and I'm paraphrasing), "download this game and add me or I'm removing you from my friend's list!"
