Crush the ice cubes in a food processor or blender.
Cover the inside of a plastic cup with sweetened condensed milk.
Fill each cup with ice to about ¾ full.
Add the snow cone syrups over the ice.
Finish filling up each cup with ¼ of the amount of each fruit.
Cover the fruit with more sweetened condensed milk.
Decorate each cup with the mango and apple slices, vanilla wafers, and add straws and spoons to each one. Serve immediately.
