A big animal that travels between the ship and the exits at a slow speed. You can jump on it and drop and store scrap on top of it just like the Company Cruiser.
Would be a perfect fit for big custom moons made for driving the CC as a backup plan or when you don't have a car. Would offer some protection from small and medium sized outdoor entities but not robots/giants.
You could add a entity or obstacle like the Vain shroud near the Ship's Ai nodes and the Entrances Ai nodes that this big creature would graze on and linger around for a while, giving you time to load on/off scrap. This also gives a convenient excuse for why the creature migrates between these spots on its own.
As for designs they need to be climbable- at least in the grazing state or at all times. It would be nice if they where goofy-aah designed like other things in LC but here are some real-life bodytypes that would fit.
Humpback-(space)whale grazing on floating schools of fish
Giant tortoise grazing on some foilage or alien fruit
Giant Wyrm worm dragon or Snake, Giraffe, Brontosaurus
.... or whatever creative thing you can come up with!
Alternatively it could Fly or not be accessible to climb during transit (giraffe,brontosaurus,dragon,giant eagles)
You could balance this by making it faster but do less trips. Some player action/item triggers it's migration?
