Prepare cake as directed with water and butter. While cake is baking, combine next 3 ingredients. After removing cake from oven, poke holes in the top with the blunt end of a wooden skewer about every ½ inch. Spoon half of rum mixture over the top. (Cover and reserve remaining glaze for serving.) Cool 30 minutes. Carefully remove cake from pan; cool completely. To serve, cut cake into 12 slices and place on dessert plates. Thread a pineapple chunk, strawberry and banana piece on each skewer; place one kabob on each slice of cake. Microwave remaining rum mixture 10 seconds; stir and brush over kabobs. Makes 12 servings.
