Putting sprouts in your head, it seems, is now a thing in China. According to The Beijinger and ShanghaiIst, folks have taken to wearing plastic sprouts in their hair, because they think it's cute. Bean sprouts seem to be the most popular.
I think it kind of looks like Pikmin, but that's me.
This, of course, is Pikmin.
According to Chinese website Sohu (via The Beijinger), the trend started at a comic or a cosplay convention, while another site (via ShanghaiIst) says a character in Chinese cartoon Pleasant Goat and the Big Bad Wolf inspired it.
The trend's origins seem rather nebulous, but reports say that plastic hair plants stuck on hair clips are being sold and worn.
