This story happens in the municipality of Izalco, Department of Sonsonate where lives a large mythological animal, half snake and half pork. Visiting the tourist centre Atecozol in Sonsonate you can find a stone image of this animal.

According to the villagers, at night you can hear a far dark squeal followed by strong turbulence under the land. All that noise comes from this animal, by which the villagers are enclosed at early hours in their homes.
