=u= I know this is just overreaching, but I just find this funny.
xD They look kinda familiar... Although, I doubt Ancel would have did this as a reference to R3, because he was working on this game during that time to have much input on R3, but still, it's funny how these remind me of Ray's sneakers. It even reminds me of the scrapped R4 concept design of the Mecha Ray picture.
But since this happened WAY after BGnE, I don't they have any connection. =u= But it was still amusing when I saw the pig's shoes just now. xD
