All models: Solid yellow body with black spots and black eyes with red iris. This is a uncataloged color for River Runt Spooks and Midget Digits, c. late 1950's or early 1960's. The related color code, SUYBS-SP is identical in pattern but the finish is matted or 'flat' finish or what is sometimes called a 'fur finish' though it isn't really furry. The Crazy Crawler is a recent special order production for the Japanese market, c. 2005.
