Russian Tortoise Help? - russian bare free

I have a female Russian tortoise PetSmart yesterday.
I had a dollar for a while, but not together on.

My problem is that when wet, it is yellow, with a strange color in the middle. The "thing" was the color of Thousand Iceland dressing (I know it's a strange comparison, but bare with me.: Q ) If my child mea turtle, with its clean white stuff "in the middle.

Is there a problem with this or is this normal?

Ten points for sure.
Thank you.
