Halloween Challenge!

[CanDLinkZz]

Just wanted a little fun thing to do for the spooky season. It’s a very basic idea, so feel free to stick some suggestions that I can add on. 
 

Your little group of creatures (as few or as many as you want, preferably mostly randomised— im making this as customisable as possible so anyone regardless of skill can join in ^^) start off on a large island, with plenty of food, but they can’t gather any yet. 
You see, these creatures have a very particular set of beliefs, and as such, they are only to eat from the food they already have in store until the very day it rains. Only then can they go ‘trick-or-treating’— which means gathering as much food as their little paws can carry! This is also the only day they can attack any of their predators— and only spooky enough creatures (Im thinking creatures with Bearyena or bat genes, but you can make your own parameters for this :3) can ward them off!
