I found someone, purely by chance while browsing Pinterest, that makes and sells Sonic plushes of various characters, INCLUDING those from SatAM/Archie!
Yes, they are rather expensive, but each one is hand made.
I figure, if I'm going to get one of these, I may as well go all in and get a life sized (3' tall) one. But, I'm a bit confused how to do that.
The site says, "You may also place orders for Sonic character plushies not shown above, or different sizes of any of the characters above. Please specify in your order form what size doll you are ordering."
I looked at the order form and the way it's set up it doesn't appear to allow me to enter a custom size or anything. Maybe someone here can figure it out?
