A friend of mine and I share rat genetics back and forth and this time he hit me up with one he knew would make me smile...

The genetics are actually black eye'd white which quite often throws masked when bred to a blaze.
The mask just happens to be blue instead of agouti like the moms mask.
The mom is a top eared agouti masked standard coat that carries blue and dumbo.
The dad is a black berkshire rex coat possum faced dumbo eared boy that I gave him.
