Hmm, dunno about that. The eyes are generally similar, or even exactly the same, when designed by Disney. If you look at sam the Eagle, the general body design is the same, but the rest is quite different. Yes the hat, was, in the concept drawings the same, but it was then changed to be an Aussie slouch hat, like the ones the Diggers wore. Thus removing the more 'Americanised' top hat to an entirely Australian one.

It is quite a classic look back to the 88 times. Pretty cool really.
