The other day I picked up this Rocket J. Squirrel figure from the flea market, pulling him out of a pile of random toys with no context as to his origins, and I have yet to discover where he came from. He's clearly old - pre 80s at least, but he has no markings on him whatsoever so tracking him down online has thus far proven fruitless.
Here he is next to a LEGO figure for scale. He's made of a soft rubber or vinyl as if he were a squeaky toy, but he doesn't have a squeaker.
My best guess is that he was broken off from a larger set - perhaps broken off a base that included Bullwinkle, like an electric toothbrush set or an alarm clock or some other goofy kitsch from the 60s or 70s.
