Make up the kool-aid ahead of time, by dissolving in a small amount on water (as little as possible). Don't add sugar! Cool this mixture.

With everything cold, mix it all together, just before the party. You can add sherbert to keep it cold, or make ice cubes, or an ice cube ring, using the kool-aid mixture. You probably won't need to add any sugar to this, as the soda, lemonade, and pineapple juice should contain plenty.
