On Sunday of the great Carnival the great fires at the great squares of the city, in Kastoria, revive at dusk. It is a pre-Christian custom that has survived in time and has come to our day.

The largest Boubounes are those of Dultso Square, Apozari's neighborhood, Omonoia square and the neighborhood of the Old Hospital. Around the lit boubouna, the attendees drink and taste treats of the day of the Carnival, consumed in view of the Clean Monday. Folk orchestras play local traditional tunes and dance until the boubouna turn off.

In homes, housekeepers keep the custom of "Haskari". After dinner, everyone is amused by the efforts of all family members to "catch" with their mouth open the boiled egg offered by a wooden stick and a thread to which the egg is tied.

The meaning of this custom is symbolic: The egg closes the mouth for the Lent Fast - With the egg its opened again on the night of Resurrection.
