Czechs already had a witch-burning fest in April (Pálení čarodějnic), and a day of dead souls in November (Dušičky), so maybe they thought their calendar looked grim enough.

Now boasting a pick-your-own pumpkin farm farm, a jack-o-lantern procession and a ball monsters would avoid, the city is truly getting into the undead spirit.
