Preheat oven to 350°F (175°C). Grease a mini muffin tin or line with paper liners. Combine fudge brownie mix, eggs, vegetable oil, and water in a large bowl. Mix until just combined and no streaks of dry mix remain.

Divide brownie batter evenly among the prepared muffin cups, filling each about two-thirds full. Bake for 18–20 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Remove from oven and allow to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

In a mixing bowl, beat softened butter until smooth and creamy, about 2 minutes. Gradually add sifted powdered sugar, mixing well after each addition. Add vanilla extract and 2 tablespoons milk or heavy cream, continuing to beat until frosting is light and fluffy. Adjust consistency with more milk if needed.

Add a small amount of green gel food coloring to the frosting and mix until evenly tinted. For a more vibrant color, add additional gel coloring a little at a time. Optionally, reserve a small amount of frosting to tint with red gel food coloring for decorative accents.

Pipe or spread green frosting on each cooled brownie bite, creating a generous swirl or dome. Gently press a candy eyeball into the center of each brownie. If desired, use red tinted frosting or gel food coloring applied with a toothpick to draw bloodshot veins around the eye for a spooky effect.
