Cut thin slice from wide end of egg so it stands upright.
Slice egg horizontally, about 1/3 up from bottom.
Place tomato slice on bottom piece of egg. Insert toothpick upright in middle of tomato slice and egg for "spine." Reattach top piece of egg.
Using dabs of mayonnaise, attach slices of olives for "eyes" and peppercorn for "nose." Attach parsely for hair and stick one whole clove on each side of egg under tomato for "bolts."
Pipe mayonnaise "teeth" onto tomato slice just before serving.
Repeat for all eggs.
