Set your Neufchatel cheese on the counter until it feels soft to the touch. Cold cheese leaves little lumps that never fully blend. I usually pull it out about 30 minutes before I start.
Place the softened cheese in a medium bowl and beat it with a mixer. Keep going until it looks smooth and glossy with no streaks. This usually takes about two minutes on medium speed.
Add the thawed whipped topping to the creamy cheese. Stir gently with a spatula until the mixture looks even and fluffy. Don't overmix, because you want the dip to stay light and spreadable.
Spoon the dip onto your serving plate and spread it into a skull shape. Aim for roughly 9 inches long and 6 inches wide. I round the top for the head and narrow the bottom a little for the jaw.
Wash and dry all your fruit very well. Slice the strawberries and kiwi, and separate the clementine sections. Dry fruit sits neatly on the dip and won't make it watery.
Just before serving, arrange the fruit on top to look like a skeleton's face. Use dark blackberries or blueberries for the eye sockets, a small raspberry for the nose, and light pieces for the teeth. Then set the Wheat Thins around the plate and serve.
