Animworm



An "animworm" is a large, brown creature that resembles an Earth centipede. Its name originates from the internal files of Metroid: Samus Returns. It can be seen in the background of Area 3, slipping through a hole in a wall with a honeycomb pattern into another hole. Being that it is only seen in the background, it does not attack Samus, nor can she damage it. As it is tunneling, one of its many legs appears to clip through the wall. It should be noted that this behavior is very similar to Botwoon in Super Metroid, Serris in Metroid Fusion, and the Fune and Namihe in Metroid: Other M. The creature appears to have an open mouth, but otherwise no sensory organs.
