Ahh persistance.

After bathing her, it shrunk almost immediately. I then left her for about 10 minutes and slowly pushed it with a q-tip. It easily slid back into her. She already seems happier. I will leave her quarantined for a week and see how she does. I know it wasn't a rock because she is on plantation soil, along with the rest of my MLFs...I've never had this problem, but after looking through her feces, it seems like there was quite a bit of the soil in it. I am now switching every frog over to papertowel. Sigh lots of work lol.

Thanks so much for the advice, will keep you posted.
