1Heat oven to 350°F (325°F for dark or nonstick pans). Place paper baking cup in each of 24 regular-size muffin cups.
2In large bowl, beat cake mix, coconut milk and eggs with electric mixer on low speed 30 seconds. Beat on medium speed 2 minutes, scraping bowl occasionally. Divide batter evenly among muffin cups.
3Bake 18 to 20 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes; remove cupcakes from pans to cooling racks. Cool completely, about 20 minutes.
4Place coconut in resealable food-storage plastic bag. Add food color; seal bag and shake to tint. Frost cupcakes with white frosting. Top with blue coconut. Decorate cupcakes to look like monsters, using decorating icing to attach candy corn for horns, banana fruit candies for mouths and other fruit candies for eyes.
