脊肋

脊 = 兆 + 月 : Joan of Arc (ji) collapsed on the ridge (脊) of the moon during her hike in the space station's living room (Ø3). A vulture (兆) is waiting nearby for Joan to die so it can rip out her spine (脊).

肋 = 力 + 月 : Lancelot (l) finds that there is a sign written on the moon (月) in the Eiffel Tower's bathroom (ei4) which reads "a solar plexus says what?". Lancelot pushes the power button (力) below, and instantly the moon punches Lancelot and breaks two of his ribs (肋).
