Take your average cake mix. Bake it up in 2 metal bowls--1 bigger than the other. One unmolded, cut the bigger one (the "body") in half, horizontally. CAREFULLY scoop out an adequate cavity in each half. FILL with well-whipped set green Jello, and reattach the halves. Frost black, arrange on serving platter. Use licorice stix as legs. Use 2 BIG green gumdrops and 6 little ones as eyes. When the cake is cut into, it spurts green goop, just like a real spider when stepped on
