Sorry for giving you possibly one of the most annoying creatures to make. But it turned out beautifully, I especially like how you kept her in quills formed in the shape of her hair while keeping them attached to her back.
Male porcupines display a strange courtship ritual, which involves dousing of the female with his urine. The urine showers are continued until the female is receptive to both the shower and the male. According to Roze (1989), "Everything suggests the urine is fired by ejaculation, not released by normal bladder pressure. Porcupines with everyday full bladders don't squirt their urine, don't have erections, and don't aim at females."
