In a 16-ounce glass, add the mint leaves and agave simple syrup.
Muddle the mint and simple syrup using a muddler or something blunt, like the end of a large wooden spoon.
Add to the glass the rum, pureed watermelon, sparkling water, and lime juice.
Mix all of the ingredients, then fill the glass with ice.
Top with a sprig of mint and enjoy!
