Pour the corn syrup onto a small plate and spread the shredded coconut flakes on another small plate. Dip the rim of a rocks glass into the corn syrup, then press it into the coconut flakes to create a snowy rim.
Add the light rum, curaçao, cream of coconut, pineapple juice, and ice to a blender. Blend on high until smooth.
Pour the blended cocktail into your prepared glass and serve.
