You take the green path, because green is the color that reminds you of nature the most, and you didn't want feel like you're parting from your nature walk.
You eventually spot something sparkling in the distance. As you approach it, you notice that it appears to be a gem of some kind. You pick it up, and suddenly, you start growing fur all over your body. Your hands become paws, and you feel something coming from just above your behind. It is a bushy tail. You move your tongue around your mouth, noticing some major changes there as well. You have large incisor teeth, and your canines are gone. You realize you've become an anthro-squirrel.
