Haha, I have pulled a few tongue sheds out of mouths, with out realizing that's what they were! My one king always has it stuck in his mouth, and I always end up pulling it out(he had rally bad nose rub before I acquired him)I always take the sheds out, just because they end up in a million pieces all over the place if I don't. So I don't give them much opportunity to do this. Maybe they got bored.
