Legend.
A few kilometers north of the city proper was a village which had become known then for its ancient tree which had a hollow trunk. It was called "Palakpak". Some villagers said that on moonlit nights they could see a beautiful, red-haired lady washing her long hair with the hollow trunk serving as her wash basin. There is also river nearby where a big fish appeared each night when the beautiful lady was around. The villagers would not catch it, believing that it must be her pet.
One day, a stranger came to the village and tried to solve the mystery about the red-haired lady and the fish. And so one moonlit night, he waited for her. Seeing the lady in her pristine glory, the stranger approached her. All of a sudden there was thunder and lightning. The earth quaked with terrible intensity, while the river swelled alarmingly into a lake. From that time onwards, that lake produces a large quantity of shrimps which when cooked, turned red. People since then had affectionately called their village "Palakpakin", after that ancient tree and the shrimps in the lake became a principal source of livelihood, which they call "Hipong Palakpakin" or Palakpakin Shrimp.
