Apparently, the one thing I like drawing more than Pokemon is Fakemon and fusions.
It’s “fur” is actually made of wax and it drips everywhere. It’s lil’ feets click-clack on the ground wherever it goes. It will chew your shoes and then accidentally set them on fire, not recommended for inexperienced trainers.
You can change the trim by feeding it special items that change the fire color (like how you can change real fire colors depending on what chemicals you’re burning). Then it shakes off the wax and it “grows” back in the new trim. As for the hat… magic.
