Preheat your oven to 350°F (175°C). In a mixing bowl, combine the brownie mix, large eggs, and oil, stirring until smooth. Pour into a greased 9x9 inch baking dish and bake for 20-25 minutes.

Once cooled, spread a generous layer of chocolate frosting over the brownies using a spatula.

Sprinkle crushed Oreos evenly over the frosted brownies, mimicking dirt.

Place candy tombstones throughout the brownie surface, pressing gently into the Oreo layer.

Scatter gummy worms over the top, letting them emerge from the 'dirt.'

Decorate with candy eyes on tombstones and add green sprinkles around to mimic grass.

Chill in the refrigerator for about 30 minutes, then slice into squares and serve.
