Carefully peel grapes and have children stick their fingers in a bowl. Tell them that theyre eyeballs. Cooked spaghetti noodles are worms. Apple peels are skin. All this with eyes closed. Then opened have them drink blood wine ( red food coloring in carbonated welches juice) or rotten brain juice (same as blood wine but use green or whatever color your heart desires and add gummy worms for an added eww factor) and brains blood and worms( spaghetti and ground beef). For desert have them eat either death by chocolate( alternating layers of brownies chocolate pudding whip cream and finely chopped candy bar of your choice) or mud pies ( a chocolate graham cracker pie crust or brownie base with chocolate pudding with crumbled brownie or oreo cookies on top... Embellish with gummy worms or whatever you please... When i think of more things i will edit my reply. Hope this helps!!!!!
