Amigurumi [pron. ah-mee-goo-roo-mee] is the Japanese art of knitting or crocheting small stuffed animals and anthropomorphic creatures. The word is derived from a combination of the Japanese words ami, meaning crocheted or knitted, and nuigurumi, meaning stuffed doll. Amigurumi are typically animals, but can include artistic renderings or inanimate objects endowed with anthropomorphic features, as is typical in Japanese culture. Source: Wikipedia.

So basically, it means knitting or crocheting a little stuffed toy friend!
