Bulborb Ocean is an area that appears in the game Pikmin the huge debt. It is so named because it is entirely underwater. So underwater, in fact, that all non Blue Pikmin aren't even able to come out from this area! It is unknown why, but enemies that you think would need to breath, such as the Red Bulborb, are able to survive even though they are completely underwater.
