Make the Olive Spider: Slice one black olive lengthwise for the body. Slice another olive crosswise into 4 pieces, then cut each in half for 8 legs. Use half of another olive for the head. Place them on top of the dip to create a spider.
6 pitted black olives
Set the Dip: Spoon tzatziki into a small bowl and place it in the center of your serving board. Top it with the olive spider.
1 cup tzatziki or any dip like hummus
Arrange the Peppers: Place bell pepper halves on the board. Stick edible eyes onto each half to make them look spooky.
3 bell peppers, 6 pairs edible candy eyes or homemade mozzarella-and-olive eyes
Fill the Board: Arrange cucumbers, carrots, celery, and cherry tomatoes in colorful sections around the dip.
3 Persian cucumbers, 6 rainbow carrots, 4 celery ribs, 1 cup cherry tomatoes
Add Extra Peppers: If you have an uneven number of pepper halves, slice one into strips and add them to the board for extra crunch.
