Lil Lebowski

My new baby horned frog! Unlike bruce, this little buddy has little stripes of green going down his back, which i think is just adorable. I got him at a pet sale (who could pass that cutie face up) and of course the guy working had no idea the species. So I *think* he's a cranwell's, like bruce. But I'm just not sure since I've never had an ornate. How do you tell?
