what do the sentimonsters organ's actually look like? are they mostly normal or is there something weird going on. I mean besides the self-healing/kind of immortality thing. do estelle and ambre find out when they're exploring each other's bodies
Sometimes your organs can be flipped. Sometimes you don't have a gallbladder. Sometimes you have an extra pituitary gland glued to the outside of your stomach. Everything works properly because the organs are all technically for show. Like you can still eat and sweat (if your parents didn't remove that in the blueprints) and stuff but as with all sentimonsters it's never for the sake of it living so much so as it is for the sake of giving off the appearance of living.
Like I keep saying. Sentimonsters have custom appearances because they were made to be able to mimic things.
Duusu is kind of stupid and she was never given enough time to look over anatomy textbooks as she should've so there will always be little quirks that vary from senti to senti like hypermobility or missing "unimportant" organs (she knows about humans needing the heart, the brain & nerves, and the digestive tract, at least. sometimes she'll blank on adding in lymph nodes or a spleen tho) or an extra bone in the pinky.
Estelle and Ambre are bad at googling though so even if they did decide to spend an afternoon vivisecting each other, they'll hit dead ends when "i have no liver" just brings up information on liver failure. We shouldn't trust them to be able to figure out the true nature of themselves by themselves, honestly. They're pop stars.
