Place all ingredients in a large blender and blend until smooth. Serve immediately.
Notes
Ways to keep your smoothie cold: Freeze all the watermelon before blending for a slushie texture OR throw in a few water/coconut water ice cubes before or after blending. *Fresh coconut water is preferred, as it is sweeter and more pungent. However, canned coconut water may be substituted.
