So since the Ah'Koi Bahnis are humanoid, I decided that's how they pooped. From there, I designed their toilet:
You enter the bathroom, and you see this one foot tall round thing on the ground. It has a lid, which is off to one side currently. You squat over this short toilet and do your business, including wiping if necessary. Then you stand up. There is no water in this toilet, and you wonder how the poop will go away. But then you see there is a button on the wall behind this toilet, with a button on it. You press this button, and the lid automatically closes. You hear the sound of high-powered water flushes. The lid then opens again, and the poo is gone.
For people who can't squat very well, there are powered seats that help you squat and then help you back up.
What I liked the best about this design, aside from the fact that human tourists would probably goggle at them, is that the Duenicallo and Shaokennah could probably use the same toilets without difficulty.
