Sure! The mechanism for how they got there is still hidden, but I can say that there is a viable way for him to get what he really needs. It'll be dropped (seemingly...) out of the sky and will land near him (unless he's in a building, then it'll land outside) in a box once a week.

...Unless it can't be kept that long, or something like that. Basically it'll drop randomly around him whenever he needs more of it.
