Ok I'll admit, I love these three babies <3
I don't really like how I drew them (proportions turned out wonky), and I haven't colored them in yet, but here's some backstory:
These three siblings consist (left to right of original designs) of Bowrain, Marshmellow, and Wirm. They constantly squabble, but when doing something serious or playing a prank, they seem to share a mind, doing things smoothly and together. They all have worm-like attributes, with Wirm being the most like one. Bowrain has a "mini-me" worm tail, Marshmellow's body is pretty long, and Wirm's head is basically that of a worm.
