Make ice cubes the night before by adding one Maraschino cherry or lime slice into the cell of each ice cube tray.
Slowly pour some lemon-lime pop in each of the cells to cover.
Freeze until fully frozen then pop them out and store in a plastic storage bag in the freezer until you are ready to use.
Add rest of cold lemon-lime pop and about 3/4 cup of Maraschino cherry juice to a beverage dispenser and stir until incorporated.
Add in the ice cubes, stir and serve in cute glasses, top with a cherry and a straw that matches the color theme of your party.
