Looks like a little tortoise figurine I have in my home office.That's an extremely dry desert tortoise. I would give that guy a warm soak right away.
On second thought, I'm thinking he has gray clay dried onto his shell, so after he's soaked for a while take a tooth brush and lightly scrub all that mud off his shell. (coconut oil suggestion still stands)
WOW - he/she cleans up nice!View attachment 271265 Clover air drying after a bath. Next update will be the coconut oil treatment
