The non Pastel babies do not look like Fires, and the Pastel babies do not look like Pastel Fires, so I doubt mom is a Fire or Fire related animal. Based on the pictures, I would be inclined to say some sort of wicked Granite, but mom really does not show signs of being a Granite. The fact that all of the babies are oddballs might be a fluke, or it might mean someone is a Super of some sort...which I doubt by the look of the mom. Might have been luck that they all came out oddballs. I would hold them all back, and breed a male Pastel cross back to mom to see what happens. They look like striped granites.....
