Raiyne

I was holding Shesha today and nearly panicked when I heard a faint gurgling noise from her. I examined her thoroughly and was able to hear the sound several more times. It doesn't appear to be at all related to her breathing (thank goodness). Apparently... she's squishy.

The sound appears to come from when she moves in between my fingers. I can feel it when it occurs. After a long time checking her over and having her move in my hands over and over again, it seems to me that she has small pockets of air under her skin. That's what it feels and sounds like to me. The "squishy" spots are random. Sometimes it's near her head, sometimes middle, sometimes the tail. I've never noticed this with her before. Could she be near shed? Does this sort of thing happen when snakes near shed?

Shesha is an '07 and is near 70 grams. I haven't seen her shed yet since I've had her. Marsha said she last shed around May 10th. I can't tell if her colors are duller than normal. Her eyes definately aren't cloudy. I fed her 3 days ago so I could have easily missed cloudy eyes while letting her digest. Then again, it took her longer to digest than normal because the hopper I fed her was pretty big. For all I know she could have some sort of weird snake gas from eating a big meal. She certainly doesn't seem sick. She's a bit flinchy, but that's pretty normal for her.

Any suggestions on what's going on here?
