Mix vanilla and banana pudding together with milk. Add cream cheese and mix with hand mixer until thickened. Place in graham cracker crust and top with whipped topping, sliced bananas and coconut. Chill for at least 1 hour before serving. You could also take one or two of the bananas and mash them up and add them to the filling along with the cream cheese. Then slice the remaining banana(s) for the topping.
