This little plush is another UFO catcher offering from the very early years of Sonic. (Right around Sonic 2, as indicated by the tag which has tails, but retains the mini walrus animal as well) This one has fairly defined figners, no shoe buckles and a bit of a square body, with quite short/thick arms. The face is pretty good, though the eyes are a bit small. The whole doll appears fuzzy and soft.
UFO catchers provided quite a large offering of the Sonic plushes in the early days.
