Hyoukaidou is an Antartica like area in the Grand Line filled with various icebergs and glaciers. It is the territory of the Achino Family and the location where the Ice Hunter Arc takes place.
Hyoukaidou is a vast area filled with mostly icebergs and glaciers. The geography is filled with various waterways for ships to pass through. However due to the unnatural movement of the icebergs, ships can easily become trapped. The icebergs that trap ships themselves are normal. This seemingly conscious movement of icebergs however is caused by various Domo Penguins pushing the icebergs across the water from underneath.
Animals
The Domo Penguin is a type of penguin that is native to Hyoukaidou. It generally resembles a blue Rockhopper Penguin with a Puffin like beak. Large groups of this penguin are able to move the various icebergs in Hyoukaidou from underneath.
The penguins themselves are very vicious. Large groups of them can cause trouble for anyone in their way.
