CRUST:

2 doz. crushed graham crackers

Dissolve each of your 3 packages Jello in 1 1/2 cups boiling water and chill in separate pans until firm - cut into cubes 1/2 inch square. Soften unflavored gelatin cold water, dissolve in hot pineapple juice, cool until slightly thickened and fold into whipped cream into which you've added the sugar and vanilla.
