Nendoroids are plastic figures of characters from anime, manga or video games. They're created by Good Smile Company and have a chibi design, which makes them look cute. You can change their facial expressions (each one has 3 faces to choose from) and their poses (thanks to a variety of arm and leg positions). I got mine from a place in Newcastle upon Tyne called AnimeZ, which sells a few of these, along with other otaku-appealing merchandise.
