Squat toilet is cultural rather than economical in Asia. You either grow up shitting sitting or squatting depending on your upbringing. There's no real standarization, and i have seen a shitty slumhouse with sitting toilet.Evidently Moona is under weight (100lb) because according to her, she shits everything out in the morning. To me, the girl in the video's that are supposed to be Moona looks well over 100lb. Sounds like she has a squat toilet, if that sheds anymore light on her socio-economic status.
But goddamit you just have to make me imagine Moona shitting everytime its like 7 A.M.
