There is more to do before you exit though. Drop in, go to the far end, and half-pipe jump to the ledge on the left. This is a large hall and you start on a ledge over a half-pipe. This tunnel turns into a regular passage. Scan the inscription above it before going through. There is a door on the far side of the room but it's the wrong color to open now, so the only way out is through a tunnel on the left as you come in. They are similar to the other Parasite creatures you've seen except they can only be destroyed by Morph Ball Bombs. You might as well get a scan of the creatures that are patrolling them though. There is a very interesting system of Spider Ball tracks above your head but you can't actually reach it now.

Beetles attack when you step onto the floor, but they should be easy to deal with at this point. Now you're in the main furnace room instead of being inside the furnace itself as before. If you time it right the bomb will lift you over the wall where you can easily get over the remaining disappearing block. Go as far as you can go to the right, then drop a bomb right as you run into the wall. You need to make a jump about half way through and that's the trickiest part. The floor of the top half is made of blocks that disappear very quickly after you touch them, and if you fall through you need to go back and take the Spider Ball track to get to the upper level again. This time, use the Spider Ball track to the left of the tunnel to reach a higher tunnel leading to the top half of the maze. That time you went through a tunnel near the floor into the lower part of a Morph Ball maze.

Get to the Furnace by following the same route you took to collect the Energy Tank after getting the Morph Ball Bomb.
