Pour pineapple with juice in the bottom of the pan. Spread blueberries over pineapple. Pour 3/4 cup sugar over blueberries. Finally, sprinkle dry cake mix over top of sugar.
Melt butter or margarine and pour over cake. Pour remaining 1/4 cup sugar over butter. Top with chopped nuts.
Bake in preheated oven for 20 minutes. Cut through with a spoon in several places to allow juices to flow through. Cook an additional 10-15 minutes. Serve with ice cream or whipped cream.
