Like the above pieces (Sonic head & Tails) this is a large fiberglass Sonic statue. Retail stores could display him in the window to attract customers.
This one has a distinctly 'oldskool' feel to it, with the big pupils, large nose and sort of fat body. It is 48 inches high. If you look near the feet, you can see he's on a base for added stability. There IS a Tails that goes with this, but it was not collected at the same time, so it doesn't appear here.
