Prepare the lime Kool-Aid with 6 cups of cold water in a large punch bowl.
Stir in pineapple juice, ginger ale, and lemon-lime soda until combined.
Add ice cubes to chill the punch.
Carefully stir in the cubed lime Jell-O so it floats like swampy flesh.
Drop gummy eyeballs or peeled grapes into the punch for a spooky touch.
Serve in clear cups so the neon color and floating decorations shine through.
