Begin by selecting a small seedless watermelon. Carefully slice a thin layer off the bottom to create a flat base for stability. Using a sharp knife, carve out a spooky jack-o-lantern face on one side of the watermelon. Scoop out the insides with a melon baller or spoon, placing the flesh into a mixing bowl. This will be used as part of your delightful Halloween fruit salad.

In the mixing bowl, combine the freshly scooped watermelon chunks with 1-inch pieces of pineapple and honeydew melon. Gently fold in the clementines, ensuring not to mash any fruit. As you mix, the vibrant colors will begin to create a mouthwatering medley. Let the mixture rest for a moment, allowing the flavors to meld before serving in your carved watermelon.

Carefully transfer the carved watermelon to a decorative serving plate. Using a spoon, fill the watermelon shell with your mixed fruit salad, packing it lightly. To enhance the festive presentation, artistically scatter blackberries around the top of the salad, mimicking little bats flying around your colorful creation. The Halloween fruit salad is now ready to steal the spotlight!

If you have leftovers after your gathering, store them in an airtight container to keep the fruit fresh. Place the container in the refrigerator, and enjoy your Halloween fruit salad within 2 to 3 days. Avoid freezing, as the texture may become compromised, making your delightful dish less enjoyable.
