When Samus first enters the room, she finds herself in a small chamber with a hole in the wall. A small tunnel can be accessed by entering the hole in Morph Ball mode. There are Pit Blocks in said tunnel that will crumble when she rolls over them. Below is a small pit that makes the tunnel head left, to the exit. Samus can use a Bomb to destroy the blocks, but she will not be able to get back to the Dark Forgotten Bridge unless she gains the Boost Ball or dies. At the other end of the tunnel is an opening to another small chamber with a door.
