Ice Hopper Nest

The Ice Hopper Nest is a boss on Excelcion in Metroid Prime: Federation Force. It is a large blue, tree-like living organism with several "maws" around its "trunk", from which it spawns Ice Hoppers and fires projectiles. This nest is likely the spawn point for the entirety of the Ice Hopper population on Excelcion. One mission sees the Federation Force attempting to destroy the nest by targeting its maws. When one maw is damaged, the creature appears to feel it through the entirety of its body. Once the nest has taken enough damage, it will disintegrate, and the unit commander will summon the Marines to an Extractor.
