Why do frogs suddenly appear 'out of nowhere' in the rainy season?

Frogs disappear during dry seasons by aestivating underground for months. Their bodies form protective cocoons, and they await the monsoon rains. Moisture and vibrations signal the frogs to emerge from their dormant state. The monsoon rains create ideal breeding pools for frog eggs. This emergence is a survival strategy honed over millions of years.
