Mark on Sulcata's Underside

[Squirtle'sMommy]

I just bought a Sulcata on December 27th. I'm not sure how old he (for pronouns' sake) is.
I've been keeping an eye on him and he seems to be doing well. He's healthy and eats and sleeps a lot. I'm not worried about that aspect.

I'm just worried about a mark on the underside of his shell. I'm really not sure what to think about it. It doesn't seem to be bothering him, but I can't be sure.
What does it look like to everyone else?
Thanks!

Hi and welcome! Aren't baby sulcata the cutest little guys? I am not seeing anything to worry about on his plastron. Just looks like some wrinkling from being squished up in the shell.
