Sorry if im a little late, but that is just pink belly from the shedding process.
It goes pink belly, blue eyes, clear, shed. It takes about 2 days to go from pink to blue, and maybe 5 days for blue to shed, although every snake is different.
You probably never noticed the pink belly thing before because its a pretty quick thing, although it is majorly scary the first time you see it, b/c It gets SOOOOOO pink! You'll notice that you can push the pink stuff around under the skin and see clear belly underneath it. Dont do it too much though: shedding has GOT to be an uncomfortable thing!!
Hope this helps you calm your nerves![]()
