If you could have any animal's tail, whose would you choose? If you chose a peacock's colorful tail, you'd be the center of attention in any room. If you had a beaver's wide tail, you would make the biggest splash at the pool. And if you had rattlesnake's loud tail, everyone would know when to leave you alone! The animal kingdom has tons of amazing tails, but your tailbone is pretty great, too!
