Place a bowl of dip at the top of the tray to represent the skeleton's skull.
Cut up 4 celery stalks to create the skeleton's arms, shoulders and legs. Lay them out from the "shoulders" down to where the hands and feet would go.
Slice the cucumbers and arrange the pieces to form the spine and the pelvic bone.
Slice red, orange, and yellow bell peppers into strips and lay them out to form the ribcage of the skeleton, layering them to create a colorful look.
Cut the large carrot into smaller pieces and arrange them at the ends of the celery stalk arms to form the skeleton’s hands.
Place small, round tomatoes at the "joints," such as shoulders, elbows, and above the thighs.
Use black olives to create the skeleton’s eyes and mouth. Keep covered and refrigerated until ready to serve.
