Chill a highball glass with ice and set it aside.
Add coconut water, lime juice, coconut cream, and simple syrup to a cocktail shaker.
Fill the shaker with ice and shake firmly for about 10 seconds until the mixture looks lightly frothy.
Discard the ice from the chilled glass and fill it with fresh ice.
Strain the shaken mixture over the ice.
Top slowly with club soda until the liquid rises near the rim and you hear a soft fizz.
Give one gentle stir to combine without killing the bubbles.
Garnish with a lime wheel on the rim.
