In a blender, combine the fresh pineapple chunks, coconut water, lime juice, mint leaves, and sugar. Blend until smooth.

Strain the mixture through a fine mesh sieve into a pitcher to remove the pulp.

Add the club soda to the pitcher and stir gently to combine.

Fill glasses with ice cubes and pour the pineapple coconut mixture over the ice.

Garnish each glass with a lime wedge and a sprig of mint. Serve immediately.
