xray: i could do a sprite variation for each womb sprite and have it toggle between them depending on whether belly is top heavy or not. would take a day to make those sprites
gingerbread xray: i would have to figure out how to juxtapose the stomach sprite and womb sprite so that they don't overlap. theoretically possible but mathematically annoying
sloshing: probably the easiest of these suggestions, i just need to find some suitable sounds
