Bathala's memory of the six moons(queens) and a previous trouble caused by Bacunawa was triggered when Bacunawa came back to attack the remaining one moon.
Explanation:
The story is ancient Philippino folklore that tells of the time when Bathala made seven moons. Bacunawa was a serpent that envied the moons (queens). His envy made him come out from his dwelling place and swallow six of these moons. This made the people apprehensive and Bathala had to surround the remaining moon with bamboo to protect it.
When Bacunawa came back again to attack the remaining moon, Bathala remembered the incident when the six moons were swallowed by Bacunawa. The people had to make noises to distract Bacunawa from swallowing the remaining moon.
