Labubu, the plush toy from China's Pop Mart is a social media darling, but the toothy little monsters are far from an overnight success.

The Labubu, by artist and illustrator Kasing Lung, first appeared with pointed ears and pointy teeth, in three picture books inspired by Nordic mythology in 2015.
