We discovered this Japanese store selling a limited edition version of the Nauga. Albeit a slightly more sinister looking one, it has a definite 'Chucky Doll' feel to it. The harsh colourway loses all the warmth and charm of the original that made it such a success too.
There is a stack more Nauga on view here. It seems the Nauga has had a renaissance in Japan. Some are still available to buy.
There's even a flickr pool dedicated to the Nauga here. Brilliant.
