Taramarga

Taramarga is a minor creature that appears a few times in Metroid: Samus Returns. It is a purple entity that serves as an obstacle, as it burrows over a door and attaches to a stone wall in front of it. While it is possible the creature itself can be easily destroyed without its protective wall, the Taramarga cannot be removed until Samus obtains the Wave Beam, which can penetrate the wall. The Taramarga's name in the Map key is not added until the first one (outside the Wave Beam's room in Area 2) is destroyed.
