I laid this frog out to inject but used too much pressure too fast when I injected the top color into the mold and the plastic went both over and under the black belly instead of just over it. The end result is pretty interesting.
Usually when this happens the whole mold full or whole cavity is shot, as in junk. This one was the exception and made for some interesting patterns of color. Red and chartreuse were used as accent colors in this one while the transparent color is rose pearl.
