I believe Zygote has one for sale, and I think I've seen one on someone's site, but I've forgotten whose is is. Just one little point, however, if you're planning on using these two objects together: polar bears are in the northern hemisphere and penguins in the southern hemisphere, and they're never together. They live at opposite ends of the Earth. Just a little FYI, so you can avoid negative comments from others if you post it. Melanie
