The wonderful world of One Piece hosts unique and wonderful locations, as well as awful places that are dangerous to live in. Some of these islands and countries caused the Straw Hat crew a very unpleasant time for many reasons, either because of the terrain of the place, the wildlife found there, or the unfriendly occupants residing within. These places have unique ordeals that they pose for individuals in the show, with some distinctive and generally unorthodox designs and terrain, making for an interesting location despite being unpleasant.
