1 (6 oz.) pkg. blackberry Jello
1 (16 oz.) can blueberries
1 (8 oz.) container Cool Whip or other brand whipped topping
2 c. boiling water
1 (16 oz.) can crushed pineapples

Dissolve Jello with 2 cups boiling water in large bowl. Add blueberries and pineapple with their juices to Jello. Allow Jello to partially set - this only takes 1 hour if the bowl is put in the freezer and stirred at 20 minute intervals. Stir the whipped topping into the Jello until completely mixed. This may be left in the bowl or poured into a pan.
