Such a shiny boyo. :D

Whoa, he looks incredible!

I love those boots! They look so good. When you put them on, Do they have something that forms around the body to form a body suit when you put the boots on?

Oh he's a mimic, so he can turn from anthro to boots, and is actually a monster than can eat you. As such he can technically just form his monsterous body around you for the bodysuit look, but it'd be more like being wrapped up in teeth, flesh and monsteryness than most other forms of living clothing.
That's also merely an example of things they CAN do, but not all mimics CHOOSE to.

He looks too cute and nice to eat you anyway. I'm sure just by his look that he is a nice, cute and friendly character

Well the adopter did indeed keep him as a cute and friendly character~ Very good hugger. Very warm, yes yes~

Awesome! Can we see what the insides of such a being might look like? :3

When boots they would be whatever lining the boot mimic wants to be, I imagine this dude would be fluffy, myself, like ugg boots.

When they're half monster so as a boot they'd be a lot of fleshy, teethy sinew and stuff that wraps around your feet/legs and gently/viciously nibbles (depending on temperament)

but there will be actual, more indepth pictural documentation on the mimic species later :D

Alright then! I'm interested!
