This one is Segaworld Sydney's Extra Large size Sonic plush. And, interestingly, it fares a bit better than their 'large', although you'll note it still has most of the mistakes going on. There's the mitten hands, belly apron, odd oval nose, wrong style of ear and large lower face but...it looks like it's stuffed a lot better and the head is much more round. The shoes are also in a bit better proportion. Are the wiggly eye tops mis-sewn or are they a product of the doll being slightly squished?

It is interesting to see how the 2 sizes differ.
