yo no creio in la lluvia de ranas, pero que las hay hay...

Raining animals is a relatively common meteorological phenomenon, with occurrences reported from many countries throughout history. The animals most likely to drop from the sky in a rainfall are fish and frogs, with birds coming third. Sometimes the animals survive the fall, especially fish, suggesting a small time gap between the extraction and the actual drop. Several witnesses of raining frogs describe the animals as startled, though healthy, and exhibiting relatively normal behavior shortly after the event. In some incidents, however, the animals are frozen to death or even completely enclosed in blocks of ice. These occurrences may be evidence for the transport of the victims to high altitudes, where the temperature is below zero, and they show how powerful meteorological forces can be. The potential violence of this phenomenon is shown by examples where the product of the rain is not intact animals, but shredded body pieces.
