>>9465194Touhou is a self sustaining fan base, so anything related to it will have some popularity by default. Fumos having meme appeal just amplifies it.
Otherwise, I guess rag dolls are an acquired taste. Anime plushies have the the backing of an established fandom to draw people from, so they can thrive even if they're expensive. Even then Dakis and Statues seem to be more popular from my limited view.
