I've completely redone whatever stupid ass shit I did with her water tummy. I have 3 body types to pick from. Body 1 is just a regular body, no water tummy, in case you don't like what I did with it. Body 2 uses the in game assets, and it probably as close to in game as I'm going to get (minus the bubbles, which I don't know how I would do currently). Because of this, it only really covers the opening on her clothes. I recommend using this one if you want to do something with her clothes on. Body 3 is a custom made water tummy. You can adjust how much/little water tummy you want with the color ramp at the end of the CanB material on that body (example in uploaded pictures). This was my first real endeavor trying to make something custom in the node editor by myself. I really like the result. Even so I highly recommend you make whatever tweaks you want to suit your preferences. I also think you can animate it to make the water look wavey/shimmery, but I'm not really sure how, so I didn't add anything like that.

I am new to doing this. Apologizes if there's something wrong with it.
