Abstract: It has recently been shown that the standard model for the formation of Uranus and Neptune cannot construct these planets at their current locations. Here we build on a recent model in which Uranus and Neptune form between Jupiter and Saturn. In our new `fairy tale', the dynamical upheaval that transported the ice giants to their current locations triggered the lunar late heavy bombardment. This scenario also provides a natural explanation for the compositional differences between the ice giants and the gas giants.
