"hero": {
"form": "one giant lime capital letter, or a pair, from a heavy geometric sans — the animal's body is the unaltered letterform",
"animalization": "add only small ultramarine details: an eye, a forked tongue, ear triangles in the counters, diagonal stripes, a beak, claws at the stem feet",
"shadow": "a hard ultramarine offset shadow down-right, like a misregistered second plate",
