BLUE TONGUE SKINKS

Hi, i woke up this morning and checked on my blue tongue, and she smells! Not a strong smell, more of like a vague smell of fish-food. Is there anything that could be wrong with her.

What part of her smells?

If it's her scales then did she walk through her poop?

If it's her breath then that is VERY odd and I wonder if she is having problems digesting her food.
