@Suiseiseki @deprecated_ii I remember in the show for most purposes they were physically the same and had the same affects as people (eating and drinking stuff, crying) but there was also that part where Shinku didn't know what a toilet was. so that leads me to believe even if they had accurate anatomy it probably doesn't serve a function for them. They probably just absorb the tea into their soul or whatever. But that doesn't answer the question as to whether it's actually there or not.
