Preheat oven to 350°F. Line 18 standard muffin cups with paper cupcake liners.
   In a large mixing bowl, combine the eggs, vegetable oil, and water. Whisk for 2 minutes. Slowly add the cake mix and whisk until combined – batter should be slightly lumpy, do not over mix.
   Divide the batter among the prepared pans and bake for 15 to 20 minutes or until a toothpick inserted into the center comes out clean and the tops spring back when lightly touched. Let cool in the pans for 5 minutes and then remove to a wire rack to finish cooling.
   Frost the cooled cupcakes with frosting.
   Twist the sandwich cookies to separate into two halves. Scrape the frosting from the middle and discard. Cut the bottom third off half the cookies. Place the smaller cut portion in a plastic food storage bag along with the remaining cookie halves. Using a rolling pin, crush the cookies until they resemble dirt. Sprinkle the crumbs on top of the frosted cupcakes.
   With the decorating icing, you can write on the side of the cut cookie that the filling used to be on if you like. Make sure that the flat side of the cookie is the bottom of your tombstone. You can write things like RIP, etc. Stick the cookies into the frosting and prop up the back with a toothpick if needed. Cut the gummy worms in half and stick a half into each side of the cupcakes. Place 2 jellybean “grubs” on each cupcake.
