Nyokki! Nyokki means "grow, grow, and grow" and that's what a Nyokki does. An adorable cast of original characters, Nyokkis are hand-made in Japan from glazed ceramic, shaped like an egg with little fabric legs. All Nyokkis are filled with a soil media and rye grass seed. Nyokki are easy to grow - seeds germinate and grass grows to full height in less than two weeks. Style Nyokki's "hair" or cut it and watch it grow again!
