Hi there!
I love
http://www.dog.com when I'm buying several of the same toys - I bought the famous "Cuz" toy on there -
I took a quick look and unfortunately it looks like they are out of stock on the 12" ones - they just have the Mini and the Jumbo - but that might be the place to go.
Just do a search from the front page for "bobo" and you'll find the dogs.
