How to RescueEdit
Shoot the switch at the top of the large door in the center of the kitchen and enter. After clearing out the enemies in the area, swim onto one of the plates as they fall and wait to be picked up. When the plates rise, they will move across and a small beam will start firing in a circular motion. Avoid the shots and the plates will either move across and dip down into the water again (in which case, repeat) or slowly lower and rise. When this happens, you will get a jump boost. Wait until this happens a second time, and you will have enough altitude to reach Blue in the center of the machine.
