Guests attending Mrp-Mrp Poo's Vector Day celebrations, held at the Boulderdash.
The Boulderdash was essentially a massive terrarium, large enough to house private parties. Mrp-Mrp Poo, the Quenk jazz musician, once hosted one of her yearly Vector Day festivities at the Boulderdash. Inside this terrarium were both a dance floor and an area referred to as the "Monotony Room." Certain walls within the Boulderdash were fitted with mirrors that did not reflect images.
