Grass? What's that?

So Mommy & Daddy took me up to Napa one Saturday. Something about wine and tasting - I don't know. While we were at a place they called Sequoia Grove Winery, they took me out of the stroller and put me down on the ground. Now I'm used to the soft rug in our house and even the tile in the bathroom or wood floors. But this stuff they put me on was weird. It was sort of like a prickly rug that stuck your hands when you try to crawl! And the weirdest thing of all, you can pull on it and it comes out in your hands!!! I didn't know what to do with it. They've taken me out a few more times to play on the grass, so I'm used to it now, but boy, that first time was weird!!
