a list of capsule contents to see whether food was explicitly available, and for some reason thought I saw machine guns on there somewhere. (The Red Ribbon Army does have a bunch of vehicles listed, but that's the closest I see.) Since it was something senzu beans - my own choice - didn't innately provide, I mentioned it. It might just have been because guns are mentioned for capsules in the OP.
Anyways, my point had been that if I wanted appliances or guns for some reason, I could just buy them with the money I could make from regrowing people's arms with senzu beans.
That said, I somehow missed that the capsule list has hoverbikes, power suits, robots, submarines, and a time machine. Those are much better reasons to pick capsules.
