In a large pot, combine the corn syrup & sugar. Heat over moderate heat until bubbly.
Remove from the heat. Add peanut butter & stir until melted & combined. Stir in Rice Krispies until well blended.
Using the back side of a greased spoon, spread the mixture into a 9"x12" pan or dish.
In a double boiler, heat the chocolate & butterscotch chips until melted completely. Remove from the heat & spread evenly over the Rice Krispie mixture, or drizzle in creative patterns.
