Hi L.
Barns and Nobles is where I got one of mine. You can check them out on-line too. Or some online thing amazon or ebay or something. If you really want a dinosaur one and can't find it, you could think about making it yourself too. I know it sounds like a lot of work but if you know what you want in it you could use your first one as a guide. Then they would be the same. Good luck.
