Using the Pen Tool (P), I'm going to draw on top of the shapes where the white fur is for the portions of the body. Instead of white, I'm going to use a very light gray (C=0, M=0, Y=0, K=10), which is because later on we're going to use white to add highlight to the fur.
Since the front legs are going to be part of the "W," I'm going to make the first "O" Poppy's head and the second her body. This makes a slight difference in her coloring.
