Making the double hets for Candy Pied

This is where genetics becomes both interesting and frustrating. If you had looked at the single recessive Punnett Square, it is a lot easier to grasp than a double recessive trait. I will try my best to break this all down so it is easier to grasp...
For this example, we will be using a visual Candy (mmRR) and this will be paired to a visual Piebald (MMrr). The first thing you will notice is that we are using 4 letters to represent the mutations rather than two. The reason behind this, down the line, there combinations than the previous. 
While a 16 egg clutch from a Ball Python is few and far between, but this is just a breakdown of how these genes will work.

The resulted breeding provides us with:
