Fune and Namihe

Fune and Namihe are encountered together as a mini-boss in Metroid: Other M in the Biosphere. They are the second bosses in the game. Samus first encounters the Namihe while running through the corridors of the Biosphere, and fights both worms in the Subterranean Control Room. Both of the creatures are identical (save for the eyes), and have the same attack patterns: they will stick their head out of the walls and ceiling, and fire energy bombs at Samus. They have another attack involving swallowing Samus and then spitting her out again. She must target the head in Search View and stun it with a Missile. This will make it come out of the wall and attack Samus. She must then finish the worm off with a Lethal Strike or another attack. She must do this at least twice to finish the boss off.

Trivia

 * This is the first game that the Fune and Namihe appear as bosses instead of common enemies.
 * The Fune and Namihe appearance and battle tactics are very similar to the Bomb Guardian as all three are worm like creatures and they also use energy bombs to attack Samus.
 * They also are similar to Botwoon of Super Metroid, in the aspect of sticking their heads out of the ceiling and walls to fire at Samus.
 * The Fune and Namihe boss battle is the only occurance of either species being found in a non-Lava area.
 * While brown ingame, they are depicted with their green and purple color schemes in Metroid Fusion in concept art.
