Ha, ha! I have the Bella doll, too. I use it for the disabled kids Piglet and I visit for animal-assisted therapy. The kids all love the doll and some of them respond better to it than they do to Piglet!
This is so funny. Stella looks like Decibel in this picture. That is so weird.
I guess it happens since they are both tortie and have some of the same markings.
In your other pictures I can easily see the difference. But not in this one.
