These young Wallonian boys from Stavelot are participating early for the Cardinal du Laetare, Stavelot's 100-year old tradition.
Every 2nd sunday of Lent, men and boys in Stavelot don white robes and masks with long nose to commemorate the day that the reigning Prince-Abbot of the Abbey of Stavelot refused to allow his clergy to join a carnival.
In case you are wondering these boys are not holding ballons. These are actually dried pig's bladders which they will use later on in the parade of the Blanc Moussis to smack people on the head. One thing I can tell you, those pig's bladders are smelly.
