Sugar apocalypse

A sugar apocalypse is a story trope in which an idyllic child-friendly setting (often referred to as a "sugar bowl") is severely devastated by a disaster that leaves most of its population in ruins.

Mainstream Smurfs Media
The only known "sugar apocalypse" setting in mainstream Smurfs media is a UNICEF commercial created for European television in which the Smurf Village has been bombed by airplanes, leaving the village in ruins and most of the Smurfs dead.
