Thread 3/4 cup blueberries onto cocktail skewers; set aside.
Divide remaining blueberries, blackberries, strawberries and raspberries among 8 tall glasses. Top evenly with mint leaves, lime juice and sugar; muddle until berries and mint are crushed.
Fill glasses with ice. Top with coconut water, club soda and rum.
Garnish each serving with berry skewer, lime slice and mint sprig. Serve immediately.
Tip: If fresh berries are not in season, use fresh-frozen GOYA® Berry Blend.
