This pretty much nails it, well done.
Maybe a bit unrealistic to have complete agency over when to go to sleep, I might have to add some house rules for that :)
It's spawns randomly near you (supposedly dropped from the rescue when they turn away)
I'm glad you liked it. Good point about the bucket blending with the helipad, that was not an intentional part of the challenge.
Every last drop helps keep the fire away.
