Companion ideas

So there has been past talk of adding companions to sub2 in the form of a robotic cat! (Btw an amazing idea!) having certain companions could bring back certain things from your inventory, like a robotic cat will bring your ores that drop, or a robotic dog will bring you back rare items you were carrying (just examples) but having them at all even without the retrieving idea, would be adorable and make you feel more attached to your world as for companions I can name a few, a dog,cat,cute little tv crab/spider with little square eyes on a blue screen, a goofy lizard, a little dolphin, or even a hovering pairate (all robotic ofc, and craftable!) only one equipped at a time for balancing/ game stability
