The Arbor Chamber is a room in the Tallon Overworld. It appears in Metroid Prime. It is a roughly circular room that is open to the sky, with a large tree stump in the middle. Hundreds of tiny orange-red mushrooms litter the floor; walking in them or shooting them will cause them to release spores into the air.
