I like the idea, a running gag made real. This remote but popular location could be improved with more installations.

Using recon-limpets on the cargo bays might spawn this new rare good, canisters full of Anacondas. Those are arguably free if you have the right equipment and can stomach the reaction...Why not a literal free anaconda? Like a literal anaconda. A rare good that's free, described as a large snake, and once you get one you can never get another one. If you ever sell it you'd get a message about how sad it looked as you handed it over, and then later in space you'd get a message that your snake died shortly after you disembarked.
We could put a bunch of other rare pets throughout the bubble so you could always get a new thing, but never the snake again unless you stole one. Some people might make zoos, but you'd have to log these things around so it's kind of impractical.
