The wrinkled skin is very common on blood pythons , usually its because the are soking for long periods of time in there water bowl , ither its because of mites or the blood ( blood pythons sometimes soke in there bowls ) just wants to do his thing " soke " and i dont know why some bloods do that stuff that looks like a strange wobbling but ive seen a couple of bloods doing that stuff , so i think its common ( correct me if im wrong )

good luck ! ! ! ! ! !
