Oums are large, hard-shelled creatures that have an appearance similar to the nautilus or prehistoric ammonite. They are found only during the events of Super Metroid, in the Maridia area on the planet Zebes. Three of them appear only in one room in Maridia, in the mechanical area near Draygon.
Depending on whether or not the game is played with the goal of getting 100% item completion, Samus may not even encounter the Oums at all. They are completely invulnerable to any and all of Samus' weapons. The three Oums block Samus' path to a Missile Station, and roll towards her, pushing her away unless she is in front of them as a Morph Ball. Because of this, she will have to jump over them with the Bomb Jump technique or Spring Ball. An Oum will sometimes pause, and then poke its tentacles out of the opening in its shell at Samus, dealing a large amount of damage.
