If she's getting ready to shed AND had a bath, maybe she did the weird inflate/floaty thing that my Richard and other beardies do. When Richard needs to crack the skin on his tummy or back so he can shed it, when he's in his bath he sucks in a lot of air to the point where he floats like a spiky hot water bottle. The inflation stretches the skin and water gets under it, so I try to leave him in the tub as long as I can for maximum benefit. Then when he gets out of the tub, while we're chilling in the reclines, he "deflates" with weird hissing and squeaking noises that can take up to an hour. Until he's all deflated he feels like a baggie full of air.
Perfectly normal and quite a hoot to watch, because he sometimes barrel-rolls in the tub cos he's inflated lop-sided and has a hard time maintaining his balance. He flails his little legs all over the place and whips his tail to keep his balance, all the time keeping his head up as high as he can.
