Add the candy corn to the vodka in a covered jar or container and let the vodka sit for 6 hours or overnight. Pour corn syrup in a single layer on a shallow plate. Add the sprinkles to another shallow plate. Dip the rim of a martini glass into the corn syrup and then into the sprinkles to coat the rim. Strain the vodka, discarding the candy corn. Pour the vodka into two martini glasses, dividing evenly. Divide the pineapple juice in half, then pour the juice carefully over the back of a small spoon on top of the vodka layer in each glass. Divide the cream in half and use the same spoon technique to add the cream on the top layer of each martini. Alternately, you can shake the vodka, pineapple juice and cream together in a shaker and pour into two martini glasses if you don’t want to layer the martinis.
