First time to see Sonic and Alvin together. Note: Their shows were once produced by the same company DiC Entertainment. And I also heard that Alvin did make a cameo appearance in one of the episodes of "Adventures of Sonic the Hedgehog." But I don't know which one it was, but its a rumor for all I know. And said that Alvin was in his 60's style in the cameo appearance.
