This is an image I chose to do as a trade between me and  BabyStar Long story short, it was originally for a commission, but due to lack of PayPal funds I offered to draw her something in return; she didn't ask for specifics, just to surprise her

The idea behind this image is partly/loosely-based on concepts in some of her images, particularly this one the most I'd say.

What is the setup, in case you can't tell?
Somehow Star has ended up either in a world where the 1-year old Gem, along with everything else, is Gigantic, even Grub. OR maybe Star just somehow shrunk and ended up with Gem. Either way, it's rather obvious Star was seen as a tiny doll and undressed perhaps left in only a baby-blue diaper.

In case you can't tell what they're saying
Gem: "YAAY! Grub likes you!"
Star: "...yippee."

I know Grub is composed of four cloudy circles but I added a fifth to make it look like Grub was curling lightly around his new tiny kitty friend/pet.

All three, (yes I said three, don't you dare exclude Grub), characters belong to  BabyStar aka  toddlergirl

Hope you enjoy this image, kitten.

P.S. I didn't add as much detail to Star because she's so tiny and...admittedly I chose to make her so adorably small. ^^;

Edit: In case you're wondering, I mean to have it where Star is seemingly smaller than even one of Grub's circles, meaning her height is less than that of Grub. (The smaller the cuter, so long as she's in view. )
