Description
The snail is light brown in color, and has a spiny center. The bumps serve to create friction if it falls on its back and needs to roll over. The shell forms a barrier from the elements. The head only comes out twice a year to look around. Otherwise it travels blindly eating whatever nutrients happen to be in the soil below it. Unfortunately, for this blind hunting method they have failed to breed to high numbers. They exist only in Ireland in a small patch of grass in the northern region. An Irish Bar nearby is named, "Head down Snails." After the famous snails that continue to mate and bump into each other aimlessly. Patrons of the bar seem to do the same. Thousands of inbreds mating and bumping into each other since Ireland was formed
