By the time the apocalypse began, they had already planned their world tour. 
They had bought an old school bus, the very one where they had met in their youth. They took their art wherever the bus could take them. And the dead seemed to love it.

Hordes of zombies followed them wherever they went. The bus was painted bright pink, a color that seemed to stir a certain unease in the undead as they trailed it for miles.

Finally, a massive explosion of fireworks marked their farewell. Illuminating the dark night, it brought beauty back to the eyes of the dead and the living. With the final burst of light, the road was swallowed by darkness, and both the bus and the countless figures that followed them vanished from sight.

Years passed without anyone seeing them.
