1. I obtained both on the same day (today).
2. I am very fond of both of them.
3. They both have some black on them.
Three reasons are good enough, though I might be able to find more. Rock is approximately the size of the space beneath the dog on wheels. The dog on wheels is approximately 2 1/4" tall and its head looks more like a goat than a dog.
