1 c. Mountain Dew soda
1 pkg. lemon Jello
1 2/3 c. water
1 c. mini marshmallows
1 can crushed pineapple, drained
1 can lemon pudding, pie filling (or 1 pkg. lemon pudding cookie)
1 (8 oz.) container Cool Whip

Mix Jello in boiling water with marshmallows until dissolved. Add Mountain Dew and pineapple. Chill until set. Mix pudding and Cool Whip. Spread over top. Note: I would use the pineapple juice and add enough water to make the required amount.
