Are Nyokki Pets for kids? Well, I don't care, those little pet plants are very cute. They are hand made in Japan, from glazed ceramic and shaped like eggs. Filled with a growing media and rye grass seeds, these Nyokki pets are easy to grow - seeds germinate and grass grows to full height in less than two weeks. They came as a set of two matching, you choose: Monkey, Chickee, Froggie, Panda or Piglet. BTW, the name, Nyokki, means grow in Japanese. (via I Guess We'll Just Have To Adjust)
