Witch

Boo pack character: a green witch with a hooked nose and a wart, long ginger hair, a crooked hat with a buckle, a jagged dress and striped stockings. She stirs a cauldron of glowing brew that bubbles while her hat tip nods; every few seconds she throws her head back and cackles and the pot boils over. Eyes follow your cursor; tap to set her off. Raymarched in WebGL, six palettes.
