Cook Pasta: Begin by bringing a large pot of salted water to a boil. Add macaroni pasta and cook until al dente, about 7-8 minutes, then drain.

Make Cheese Sauce: In a medium pot, combine milk, cream cheese, and shredded cheddar over medium heat. Stir for about 5 minutes until smooth and melted.

Color the Sauce: Add a few drops of green food coloring to the cheese sauce, stirring to achieve a vibrant hue. Optionally, add purple or black food coloring.

Combine: Add the drained macaroni to the colored cheese sauce and stir thoroughly to coat each piece evenly.

Serve: Transfer to a serving dish and top with candy eyes for a fun presentation. Serve immediately.
