In a large punch bowl, prepare the lime Kool-Aid with 6 cups of cold water. Stir until dissolved.
Add pineapple juice, ginger ale, and lemon-lime soda, then stir gently.
Drop in ice cubes to chill the punch.
Carefully stir in the cubed lime Jell-O so it floats like swampy “flesh.”
Add gummy eyeballs or peeled grapes for the spooky zombie effect.
Ladle into clear cups so the neon color and floating decorations show through.
