Looking for a toy for my daughter

I've been getting my 2 year old and 4 year old daughters into works of Miyazaki (My Neighbor Totoro, Kiki's Delivery Service and Laputa). They've got the plush Cat Bus and Totoro and love the music. Right now they're into Princess Mononoke and I want to find them a Kodama toy that makes the rattling sound. I tried a search but can only find plushes or statues. Does anyone know of a noise making Kodama toy? They can't be that difficult to make, can they? Thanks.

You can pick them up through Hobbylink Japan. I have bought many of my Studio Ghibli items for my kids there; They use DHL for shipping and you usually get items within two weeks of ordering from them. A great place to shop.
