1. At the very beginning of the level take the elevator and ride it down.
   You will soon see a ledge to the right.
   Ignore it and go to the ledge below, also to the right.
   Make a water Fluro to stand on the switch, then go up to the previous ledge to get the blob. (0:50)

2. When you get the Liquid Luminescence Journal entry, instead of heading to the right go down below where you guided the Fluro to flip a switch and drop down the ladder. (4:45)

3. After you fix the 3rd extractor, you will enter a new area and you'll meet the Dark Fluros.
   If you spray the ground near them with the Green goo they run away.
   You need to make them run all the way to the top of the platforms to flip a switch and drop the protoplasm. (14:50)

4. You will see this blob high on a ledge.
   The only way to get this is to create a Drinker seed (the one that goes after its own material) and use Protoplasm as its liquid.
   The Fluro will climb the ledge and eat the Protoplasm.
   Now just spray some Protoplasm on the ground and he will come down for you . (28:10)

5. This blob is near the end of the level when you go down the stairs with numbers and it is past #6.
   You'll have to fix all 6 extractors to unlock it. (34:15)
