Prepare all the fruit: slice the oranges, green apples, and watermelon.
In a large punch bowl, combine the cranberry juice, orange juice, and pineapple juice.
Stir the mixture well to combine all the juices.
Add ice cubes to the bowl to chill the punch.
Slowly pour in the ginger ale for fizziness.
Add the sliced fruits: oranges, apples, blackberries, and watermelon.
Gently stir the punch to distribute the fruit.
Add gummy worms on top for a spooky touch.
Let the punch sit for a few minutes to meld flavors.
Serve in cups and enjoy!
