Flaahgra Tentacle

From Wikitroid, the Metroid wiki

Flaahgra's Tentacles protect the four weak spots of Flaahgra. They guard Morph Ball slots which Samus Aran must lay a Bomb in to damage Flaahgra. They disappear (interestingly along with the pathways they were being held in) once you bomb the slot they were guarding.
