Make the gelatin according to the directions on the box. Pour into a 9 x 13-inch pan. Refrigerate at least two hours.

Unwrap the SNICKERS® Brand Miniatures and chop. Make the cake mix according to the directions on the package. Fold the chopped candy into the batter, before transferring it to a 9-inch square baking pan and a 1-cup bowl.

Bake the large and small cakes in a preheated 350-degree oven—the 9-inch square for 35 minutes and the cupcake for 20 minutes.

Once cool, place the 1-cup cake on top of the square cake. Place the cake on a large platter. Cover the cakes with vanilla frosting. Liberally sprinkle the cakes with ground vanilla wafers.

Using the printable template, cut palm leaves from the green fruit leather. Place the leaves on top of 5 TWIX® Brand Miniatures with a dab of decorator’s frosting, making palm trees. Arrange the trees on the cake in a cluster. Dot brown M&M’S® Brand Milk Chocolate Candies with decorator’s frosting, and attach them to the palm trees.

To make crabs: Place three orange M&M’S® Brand Milk Chocolate Candies in a "V" shape. Using the chocolate decorator’s frosting, outline claws on 2 M&M’S® Brand Milk Chocolate Candies. Dot chocolate decorator’s frosting for the crab’s eyes. Make several crabs, and arrange them around the cake.

Cut the gelatin into 1/2-inch cubes, and scatter the cubes around the cake as if they were water.
