Hawaiian Polynesian lava sunbather figurine

Not sure exactly if these are a sort of Tiki God or something, But is probably a Hawaiian or Polynesian souvenir item. It appears to be male, but has poined ears (like Spock), bushy eyebrows and and mostly bald on the very top of his head, with just hair arounfd the lower part of his head. Nude, and made of black lava I believe. Not a real handsome guy but he seems to be enjoying the sun! Measures 5" long. I have another that is similar I will be listing.
