These are large plushes (thats an AA battery by the foot) with a great & fun property: you can pose them. They have a pose-able frame inside, so they can stand and keep poses too. These are sometimes called 'big-foot' dolls because of their large feet. They were abundant on ebay around the time of Sonic Adventure 1. The tag appears to be in Chinese though...but it has all the copyrights. Each one also has a button on the side (see top right) which is acrylic with a hologram copyright inside (detail at left). Holograms are rather expensive, so it's unlikely a bootlegger would go to the trouble to replicate it.
