Oh yes, she really likes the wiggling belly type too

This makes me wonder, how is her digestive system set up? Multi chamber like an orca or more simpler?

Oh, I didn’t know that orcas have a special digestive system (or I forgot and can’t find the article). Can you tell me?

I kind of have a tutorial for that more or less. Here is a comic a friend drew with a description by me that follows a prey through a dolphin (same system layout)

In short:
-The gullet opens into a forestomach. No acids except whats leaking in from the next chamber. Rough walls, no slime on them, grind down the prey into a kind of chunky stew
-Food then moves back up but instead coming up the gullet it makes a turn to the side and drops into the second stomach, the main stomach. This is the "normal" one. Slimy walls, acids, gentle kneading. Prey is melted into smooth paste.
-from there it goes into the pyloric stomach which simply miyes in enzymes allowing cetaceans to quickly absorb the huge amount of nutrients sloshing through their intestines. (In the case of fully grown orcas several hundred kilos a day. For sperm whales, 2 tons a day is not out of the possible)

Oh wow, I see, what a complex and interesting sequence. Probably, with a competent play on the fact that those who were not needed did not turn into mush, this sounds interesting... But if one day I need to draw this, then I will get confused myself xd

Feel free to poke me then. I would gladly help out with a few googled refs or advice. I talked a few people into drawing these quite nicely in the past ^^
And I think at least the first two chambers could be really fun to have. Imagine a storage-ish stomach that runs on a timer because the walls are so abrasive.

Thank you! If you want to persuade me, it’s unlikely that you will have to ask for long, I love new experiences x) Besides, I don’t remember drawing a digestive system that differs from the standard one
Yeah, that sounds fun!

If you want, send me a note and we can brew up some ideas. The standard dolphin gurgle system is fascinating as it is, but we can tune it a bit to fit your Ymir's needs.

That is super cute to see! Loving this!
