In a large punch bowl or pitcher, combine the lemon-lime soda, orange juice, and pineapple juice. Stir gently to mix.
Add scoops of orange sherbet directly into the bowl. The sherbet will begin to melt slightly, creating a frothy and spooky swirl.
Ladle or pour the punch into glasses or cups.
Top each glass with a swirl of whipped cream for a sweet, cloud-like finish.
Garnish with Halloween-themed marshmallow candies or decorative sprinkles if desired.
