This is another cool recipe from my mother in law's cookbook.
Ingredients:
1 pint Cool Whip
1 can crushed pineapple (16 0z)
2 Cups mini marshmallows
1/2 cup chopped walnuts
1 small package pistachio pudding (use it dry)
1 Cup coconut if desired
Add the pudding to Cool Whip then add other ingredients.
