Big Brother Naija Shine Ya Eye housemate Nini has been tasked to prank housemates by exiting the house for 24 hours.
Nini is one of the housemates up for eviction ahead of Sunday as the show gradually enters its final week.
During her diary session on Tuesday, the 26-year-old model was instructed to carry out the task as a top-secret.
Biggie said: “Upstairs in the games lounge, there is a secret emergency exit. Tonight, while all the housemates are asleep, you are to use this secret exit to leave the House.
“You will stay out of the house for twenty-four hours before returning back.
“Nini, this is a top-secret mission. This means you cannot disclose it to anyone in the House.
“The secret emergency door is the window right next to the trophy cabinet. All you have to do is to stand next to the window when you are ready to leave the house, and the window will automatically open for you.
“Upon your return to the house, you must not tell anyone in the house that you left the house. When questions are asked, you must feign ignorance.”
