I have seen several T's do the mud pie thing and can only guess that it's their way of trying to adjust the humidity where they want it to be. Most of my drier species like the Brachys do it but occasionally even a wetter species will do it also so it doesn't really seem to follow any set pattern.
Glad ya managed to calm her down. They were far from calm when I was moving them into their containers after they came to me. But I am the 1st to admit that even a so called nasty one can be handled as long as you move slowly and have a clue what you're doing. Nice pic by the way.
The pic of Swifty's female isn't faded brown because it is a fresh molted adult female. The one in my 1st pic is only around the three inch mark and Joy's needs to molt. I have a female that looks like Swifty's as well she just isn't as fresh and thus doesn't look as vivid.
Mine has a wonderful personality, though I don't think that's common in the species. I can carry her around any old way and she just sits there. They're supposed to be aggressive, but I haven't seen it yet. I'm sure I will, though. I may try to find her a man someday.
