Growing up can be itchy business.
While many other beings may not look at your redfoot tortoise shell and see a living organism, you know differently.
Your keratin-covered, bony shell, which is attached to your spinal column and skeleton, is literally what holds you up.
When it grows, you grow….whether you were particularly wanting to or planning to or not.
And when things decide to grow, sometimes they itch.
This is a great reason to hire a large shell-less assistant, by the way. You can train your assistant to scratch your itchy shell so you can feel better right away.
