Magdollite

Found in the Norfair section of Zebes, Magdollites are strange creatures that appear to be "living" columns of Lava. Normally they are found resting at the bottom of lava pools, in which their green eyes and teeth can be clearly seen, but when something comes near it the Magdollite will stretch itself into a tall column of magma, equal in height to whatever it is preparing to attack, and it will then throw part of itself at its opponent. After its attack it will sink back to the pool of magma. These creatures can be frozen with the conjunction of the Ice Beam, and are vulnerable to Super Missiles. They resemble Magmoors in their combat tactics.

Metroid: Other M
Magdollites are given a huge makeover for Other M. They now have arms and mouths, and can shoot large molten rocks at Samus.



Super Metroid manual
"Magdollites have the power to turn into magma and change shape at will. They attack by tossing lava."

Super Metroid Nintendo Player's Guide
"These lava columns spit some of themselves at you."
