News Power made 3 sizes of this particular pattern for classic Sonic. This is the 'medium' doll. And...it's ok. Sometimes proportions can get a little wierd on pattern changes. The thing that's a little out of hand here is the flat flappy felt for the spikes, especially the top one. It's becoming really giant. The hands & shoes though are a good big size/normal looking.

His body is a little large/belly dot size is also large compared to the blue area. The head shape is ok, as is the mouth/nose & eye shape from the front. You can see the size of him with the hand in the photo, so you can see he is squarely in 'medium' on their range of plushes. It's not an amazing doll, but it's an ok collectible that was probably average and normal for the time it was made.
