Here's my entry for the ratio editable. I will take screenshots of all different options and put them here. My final plan (so far) is this:
-Grown rat
-rat's nest with three different babies
-accessories (just a collar, I think. Unless you're interested in anything else.)
-I'll try my best at a couple backgrounds
-Treats
-Naked rat, if I can remember
All rat colors are just default colors, and can be changed with ease.
