The Bats & Snake Temple

During a visit to Bali, we were traveling around and found this temple in a cave at dusk, called the Bats & Snake Cave. I recall I commented to some local guy about the symbology associated to bats and snakes in local folklore and he simply negated and pointed inside: "there's the snake" to a REALLY HUGE light green snake moving inside, and out when the sun and a cloud of bats a-la-Batman flew out of the place in a second "and here are the bats". Served me right, too :D
