Bara (but is rarely nicknamed Rose) is an Bydo organism that can only be found underwater, especially underground sewers and the flooded energy reactor. It attaches itself to non-organic (or organic) surfaces and stays there. It remains totally stationary while emitting Bydo Shots at intruders who dare enter the murky depths. They can sense nearby danger that approach them quickly.
