The Boulderdash was a building-sized terrarium in which private parties were thrown. The Quenk jazz artist Mrp-Mrp Poo once organized one of her annual Vector Day gala at the Boulderdash. The terrarium contained a dance floor and a space known as the "Monotony Room." Some of the Boulderdash's walls were covered with non-reflective mirrors.
