Blast Furnace Observation

Blast Furnace Observation is a room in Pyrosphere in Metroid: Other M. The room is a facility suspended over a pool of Lava. A small hatch in the floor leads to an underground chamber with a Morph Ball tunnel. This tunnel is suspended over the lava and features several Grapple Points in the way. Samus must Bomb them to release them. One of them is swallowed by ULF 28. Samus then battles the creature, and it flees.
