Here is a page from the Nanco Nancy item catalog. That company produces dolls ONLY for prizes or carnival games. They range in size from about 9 inches to 41+ at the largest. (Giant dolls are always attractive at carnival games) The yellow caution sign says how they can't be sold at retail. The little charts explain the different doll lengths for each one available. You can see they've got Shadow, Sonic, Amy & Tails available. Their tag is pictured at the top. You may be able to see a catalog at this page Nanco Nancy Catalog, with other dolls. Tails has a big mouth, but everyone seems fairly proportionate, though their socks may be too small.
