Info on the VistaQuest 8920?

I was looking at an underwater camera at Walmart.com, and it just looked like a plain digital camera. I was wondering if it came with a cover or something, or if it was already water proof? I don't want to order it and then find out I have to buy a case separately as well. Please help? If you Ned a reference, just go to the Walmart website and search underwater camera or vista quest 8920 or whatever, it should be the first option, it's red. Thanks!
