Preheat the oven to 350 degrees (F). In a large bowl, combine the cake mix, eggs, mandarin oranges, reserved pineapple juice, and mayonnaise. With an electric beater on medium speed, beat for about 5 minutes or until blended. Pour into a 9" x 13" baking dish that has been coated with nonstick baking spray. Bake for 25 to 30 minutes, or until golden. Allow to cool thoroughly in the pan. In a medium-sized bowl, combine the whipped topping, pudding mixes, and crushed pineapple; mix well with a spoon then spread over the top of the cooled cake.
