Remember Frosty the Fire-Breathing Snowman? This is Sparky the Snow-Melting Dragon. He was built by Nick and Anna—the folks who made Frosty—and he's helping them deal with a snow-filled driveway.
Note that I don't know what these fire-breathing beasts' real names are, but I think Frosty and Sparky seem fitting. [Thanks, Nick and Anna!]
