Breed two very bright Sunglows together. It's line breeding, the better quality animals you breed, the better you will get.

The brighter the Sunglows, the brighter their offspring will be. This can only be achieved by breeding the brightest and best looking offspring together for many generations until the desired appearance is attained.
