The Cave Cruiser is a docile member of the Naedocyte family. They seem to mostly just float around sucking up static charge from the surroundings, and being mostly oblivious to the happenings around it. Harmless.

~ Miner's Manual Description
The Naedocyte Cave Cruiser is a passive creature found exclusively on Dense Biozone. It floats around aimlessly, occasionally raining a substance that has no effect.
Players can stand on top of the Cruiser and use it as a floating platform, making them avoid some enemies. Caution should be taken that the Cave Cruiser isn't accidentally killed and that no ranged enemies are targeting the player.
