OK, now my mind is racing.
Humpty-Dumpty might have been an alien or cryptid. Maybe Rapunzel had shape-shifting abilities? And maybe there was something on the top of the hill that didn't want Jack or Jill from nosing-around, seems that someone should be familiar with their daily route to their water source. What are the chances of both falling at the same time? Smacks of a force-field. Don't get me started on blackbirds baked in pies. That's a Stephen King story right there.
