Preheat the oven to 350 degrees. Spray a 9 x 13 pan with baking spray and set aside.

In a large bowl combine the brownie mix, eggs, oil, and water. Mix well to combine.

Pour the brownie batter into the prepared pan and bake for 30 minutes.

Remove from oven and cool completely on a wire rack.

Once the brownies are cool spread the frosting on top of the brownies.

Combine the food coloring and water in a bowl and mix well. Dip a small tipped paintbrush into the mixture and hit it on the edge of the brownie pan to create a blood spatter. Continue doing this all over the brownies.

Place the gumball eyes on top of the brownies.

Cut into squares and enjoy!
