Puromi are an enemy encountered in Super Metroid, in the lower levels of Norfair surrounding Ridley - they are confined to a single room containing many breakable pillars and continually rising lava. Each individual consists of a line of eight large, glowing orange spheres which "leap" out of the lava in a low arc, passing unhindered through walls and obstacles and damaging Samus should she come into contact with them. They are impervious to all weapons, although the Screw Attack allows Samus to pass through them without taking damage. They are only named in the game's debug code.
