Here’s something that is not Bionicle, for a change…
“It is normal when first piloting a PRAWN suit to feel a sense of limitless power at your fingertips. Professional PRAWN operators receive weeks of training to counteract this phenomenon. You will have to try not to let it go to your head.”

The P.R.A.W.N. Suit (Pressure Re-Active Waterproof Nanosuit) (Mk.III) is a powered suit of armor, designed for use in both the deep-sea and space - capable of affording protection to a pilot whilst maintaining maximum dexterity with hydraulic limbs and a reinforced canopy. It is however not directly worn - rather it is a large frame that can be piloted in a seated position. Unlike the other vehicles in Subnautica, the Prawn Suit walks along the ocean floor, only using thrusters to move vertically.
