Always feels weird to do requests when I can draw my characters just fine myself, but … Maybe Sweet Tooth or Dr. Crazystein?
Dr. Crazystein:
A very unusual fluffy who wants to be a mad scientist, constantly wanting to do experiments with whatever materials he has available. He also doubles as a doctor, capable of applying band-aids and stitches. Has poor vision in his purple eye. Surprisingly not into sketties or hugs or fluffy crowds, he only cares for his science.
Dark humor, hugbox and moronbox are good fits, or any scene from his story.
Sweet Tooth:
A candy-obsessed fluffy who has a variety of sweets stuck in her fur at all times. She has no pupils and her fur has swirls in it. Has eaten so many sweets that her guts are made of candy. Toon physics extraordinare.
Hugbox, candy gore and joke abuse (think Tom and Jerry-type slapstick) are good fits for her - anything toony or sugary.
