A Terri, that looks great!
I've had a couple of dinosaur bone collectibles spawn at the edge of the swimming pool. Each time the peep I dropped to collect it went right through and landed in the water!
The second time it was a rare piece that I hadn't found before. You may have noticed that with new fossil items the peeps take a little longer to dig them up. In this case she disappeared from view completely (not even her head was showing) for 30 seconds or so; I got quite worried!
