If you put a powder keg down in darkness right within reach of the custom Flower enemy from TSS, it flickers bright and then back to dark each time Beethro moves. I can't tell what exactly is causing this, but it definitely seems to have something to do with the adjacent Flower; this doesn't happen without it.
Making the entire room darker instead of putting a darkness tile on top of the keg doesn't cause an issue, but making a further darkness tile beyond the room's Weather-set darkness does.
This flickering happens if the conquer token isn't present too (i.e., if the flower is told to just stop and not appear), but less frequently.
