In a large pitcher, combine green apple juice, pineapple juice, and orange juice.
Gently stir in club soda and ginger ale to keep the bubbles fizzy.
Add green food coloring if desired, and mix until evenly colored.
Fill each glass halfway with crushed ice.
Pour juice mixture into each glass, leaving a bit of space at the top.
Drop in blackberries, blueberries, or a maraschino cherry for a spooky vibe.
Garnish with lime slices, mint leaves, and a gummy worm for a “mummy” look.
Optional: drizzle grenadine inside the glass before pouring to create a creepy red swirl effect.
