You're not the only one to try to source that animal or it's descendants. It appears that it died young and never bred, although I have to say that I was told this by a breeder in the states although who I can't remember, too long ago. I don't believe it was a doctored pic, there are similar high yellow animals in closely related species such as radiated rats which are available. As for albino trinkets, I've never seen or even heard of one but I have heard of people with hets that never produce albinos...
