Check out this clockwork polar bear automaton, probably European made and dating to the turn of the century. This automaton is currently available on ebay.
From the eBay description:
When wound, this Polar Bear walks along on all four paws, opening and closing his mouth to flash his teeth, then suddenly stop and rear up on his hind legs again opening and closing his mouth to scare us with his teeth, then he’ll drop down on all fours and walk forward starting the cycle over again!
