Whats up with him is that He is a GREAT example of the morph.
What you see is a lot of peole buying Mojos, just to buy a mojo. They dont take into effect that crappy colored mojos make crappy colored snakes (generally speaking, always up for debate).
When you get clean animals, and breed because it is a beautiful snake, you are in fact selective breeding for that particular trait.
My mojos, have a green tint to them, with almost NO yellow.
Other mojos' have high popping yellow....but generally fade out as the baby matures.
