Murphy

You stumble upon Murphy in a ruin, collecting & polishing rocks with bits of crystals mixed within. Startled at your shadow, Murphy puffs up & hisses. Wiggling its body like a cat & pounces on your shadow, bewildered when the shadow doesn't react. Finally Murphy turns & sees you, towering over them. Putting on the bravest face Murphy can muster they growl & in the most adorable voice, demand you identify yourself.
