To make these the process is a bit more involved: In a food processor or blender puree the watermelon and then pour into the bottom third of the Zipzicle bags.
Stand them upright in a cup and freeze.
Once frozen, mix together the coconut milk and honey/maple syrup. Pour that mixture into the second third of the Zipzicle bags and then freeze.
Once that is frozen puree the blueberries and pour into the final third of the bags and then freeze.
