Line a 9x13 baking dish with parchment paper.
Melt your butter.
In a mixing bowl combine your graham cracker crumbs and melted butter.
Press the crumbs into the bottom of your lined dish.
In a large mixing bowl using an electric mixer whip the cream cream.
Blend the whipped topping into the cream cheese.
Separate the cream cheese mixture into 3 bowls.
In one bowl place the raspberry portion of the sherbet, in the other the lime portion of the sherbet and in the final bowl the orange sherbet. It is okay if you get some of the other flavor sherbet into your bowl.
Using the electric mixer stir up each bowl.
Next pour your lime mixture onto the crust.
Next the orange.
Finally the raspberry mixture.
Using a butter knife carefully swirl the flavors together.
Place into the freezer for 8 hours or overnight.
Slice and serve!
