Oh God, that sounds terrible!
Um, well, she had an incomplete/poor shed. So some of it is still on her back, but all from her belly and lower half is gone. I'm soaking her tomorrow (because it won't be 48 hours after feeding until late tonight, and I'll be at work). I've misted the tank daily, sometimes twice a day, getting the humidity to 70-80%, but then it falls back to around 60%.
The substrate is dry, and I actually thought it was Reptibark, but I just grabbed the bag and it's "Zilla Bark Blend - Premium reptile bedding and litter for chameleons, frogs, snakes, skinks, rainforest geckos". The back of the bag says it'a 100% organic, and "contains premium ground bark of fir trees. Because the bark holds moisture, it is an ideal ground cover for tropical and forest habitats."
My BP is in her hide now, but I'll go get her out and take a photo of her belly and upload it here asap.
