 From that moment on, Tenten continues to manifest itself through earthquakes and volcanic eruptions, while Caicai causes tidal waves and floods when he rolls over during his sleep.A variant of the myth tells that Caicai's anger against human beings began because a girl rejected her son, the Trauco.Some Huilliche communities of Chiloé say that the battle originated because a daughter of the Trauco rejected the pillán Peripillán, and for this reason her son decided to take revenge.
