Slime on my pacman frog?

i've got a young pacman frog, and it's my first one so i'm still concerned about everything i do for her. i'm starting to think she's just shedding though. she's got her self buried most of the time and i get her out to feed her and that's pretty much all she does. every now and then she'll get into her bowl of water and sit out for a while, but lately she's been buried constantly. i noticed that she had a sort of clear slime on her, and when i'd clean her off with water, it'd roll right off of her. it's the first time i've noticed her having that on her. i was wondering your thoughts, thanks.
