Just a quick ref to get down what Sparky's design looks like for a suit that is gonna be made!

His chest marking is like an "X" in a way, just no light blue in that space to make it look like a complete X. Gold eyes with somewhat slit pupils, lavander claws, two chips on left ear. Bright blue/cyan horns.

He's an odd hybrid, a raccoon/feline/nudibranch. Nudibranchs, for those who don't know, are really awesome colorful sea slugs. Look them up! The little fox tail-like things on his back were inspired by the strange features known as 'cerata' on nudibranchs like these:

He has four locations on his back(shoulders/hips), each with a cluster of three 'cerata'.

Anyway, that's sparky!
