The Bigfoot Fish is a hybrid version of American legend and goldfish.
Due to it's relatively small population, Bigfoot Fish trawls the depths of the ocean using it's one hairy foot attached to the top of its' head to proper itself. Due to its' design, the Bigfoot Fish, it often drowns due to its' need to remain upside down to walk along the bottom.
