American Sonic Action Figures
These include true action figures as well as bendies. All of these are a fairly recent addtion to the Sonic the Hedgehog merchandise world. Unfortunatly, they are not so recent that you can expect to find them in stores today. Your best bet is Ebay, but some of these are becoming rare and collectible. If you have some, hang on to them, as prices (especially for ReSaurus) are rising!
This Just In: The Toy Island figures are being re-released and re-packaged with LESS accessories as a "Sonic X" line. These were originally from Sonic Adventure.
