Add the sherbet, 5 cups of 7UP, pineapple juice and fruit punch to a blender or food processor and mix to combine.The mixture should be slushy...add a little Hawaiian Punch as needed to get to that slushy state.
Pour into a pitcher or punch bowl and stir in the remaining 7UP.
Notes
If you don't have a blender/food processor to handle the full amount--halve the recipe and do two batches. Combine in your pitcher or punch bowl.
