Attendees at Mrp-Mrp Poo's Vector Day celebrations, hosted at the Boulderdash.
Private gatherings were hosted within the Boulderdash, a terrarium of immense size. At the Boulderdash, the Quenk jazz musician Mrp-Mrp Poo once held one of her yearly Vector Day celebrations, which occur annually. Included within the terrarium were a dance area and a space referred to as the "Monotony Room." Some of the Boulderdash's walls were constructed using mirrors that did not reflect.
