On launch night, eighty-one potential housemates stood near the crowd waiting to find out who would enter the House by being chosen by Big Brother, live. Big Brother selected thirteen housemates, whilst the final, fourteenth housemate was chosen by a random draw held by Davina. Mario won the random draw, however, Big Brother set him an "Impossible Task" upon entry. He was forced to work undercover as a mole, interfering with the House in a forced discretion for four days. If the majority of the housemates suspected him as a mole, Mario would receive an immediate eviction. He entered the House with a mole suit and a sign saying "I AM A MOLE" to draw housemates to fast suspicions. In the later hours, Mario got access to the Mole Hole, his living quarters located in a door at the garden.
