My family has used one that's simular.
One large pkg of Jello, two cups hot water, mix well. Add one 8 oz pkg cream cheese and use a fork to break it up into little pieces in the hot jello. Add one can drained crushed pineapple. Add 8-12 oz of any soda that goes well with your flavor (ex: black cherry jello with cherry cola or Dr Pepper, Lime jello with 7 UP).
