Liquid Phazon is a semisentient puddle of Phazon. It can move across any surface, and can slightly change its shape to avoid attacks. They expel their young, Phazon Grubs, as they move for defense. Touching them in Morph Ball mode results in Samus being covered and damaged by Phazon. They are found on Norion and the G.F.S. Valhalla.
"Liquid Phazon appears to be a semisentient glob of Phazon. Their young are known as Phazon Grubs, and eventually metamorph into their adult, or 'puddle' form. They exude a toxic chemical to protect themselves from predators. Contact with the substance can be deadly. They can alter their shape in a limited fashion, usually to avoid incoming attacks."
