I don't like designs with snot hanging from the nose. I remember in The Legend of Zelda: The Wind Waker there was a kid in the beginning with snot hanging from his nose that bounced around, and he'd chase you! I found it repulsive. One of the younger shinobi in Naruto also constantly has snot hanging from his nose. I don't know if Japan thinks it's cute or if it's a way to denote a young child, but it's disgusting.
