Anyone know if Calico/Sylvanian does parts orders? Occasionally I'll see an interesting accessory that would work with a Playmo project, but invariably I don't need the whole set.
I think not. Geobra must be the best toy manufacturer on the planet for supplying spare parts (Lego might be better, but I know very little about THAT toy!) which coupled with the fantastic resource which is PlaymoDB makes the tracking down of specific parts a realistic possibility. I suspect Lego probably is even easier to get spares for with sites such as Bricklink (what happened to that idea to do something similar for PM?).
Sylvanian Families is big in UK (my daughters love it, I don't 'do' fluffy bunnies) and searching on ebay.co.uk for spares is sometimes worthwhile.
