In celebration of spooky season, McDonald’s is reviving its iconic Happy Meal Boo Buckets — an annual tradition that the fast food chain first introduced nearly 40 years ago. This year’s trick-or-treat-ready buckets are “getting a refresh,” much to the dismay of longtime Boo Bucket collectors.

In addition to the toys—which are sure to become highly coveted collectibles —the Happy Meal also features an exclusive new dipping sauce: Monica's Marinara Sauce. One Reddit user who got their hands on the meal said it's "the best sauce that McDonald's has ever produced."
