You've seen various Kelly Toy plushes around these pages before, but you havn't seen the 54 inch one! This one is super big, but it is not their largest, which is a 72 inch. (Sonic, Tails, Amy, Knuckles & Shadow seem to have been made at each size level) As with most of their dolls, he looks ok, if slightly/somewhat under-stuffed. The feet & hands are appropriately big/don't seem shrivelled like on some dolls. His ears are a tad low on the head, and for some reason the brow ridge is a cloth 'flap' type thing with this one. The eyes are properly placed, and so is the mouth though, so the expression remains decent. This was a win-able item at Six Flags theme parks in the USA. 

The photos in the gallary give you more of an idea how this giant doll looks. The eyes are embroidered on, and you can really see the size of the hands (though they are flat) His spikes have an all-right arrangement, however, they're not perfect. The wooden chair you see there is a regular size
chair, and the light blue doll he's holding at the right is the BIG Jazwares one, so you can get an idea of how big this really is!
The cloth is rather light-weight, similar to t-shirt material. The large size makes him succeptible to pulled stitches or rips, so you have to be careful & keep this doll away from pets or anyone that would pull on him.
