Big Brother Naija Season 10 housemate, Kay Bobo, on Monday evening, secured a guaranteed spot in the finale after answering the mysterious red phone in the house.

The call by a Big Brother Naija representative with a feminine voice, which came with a shocking twist, offered him immunity at the cost of ?10 million deducted from the eventual prize money.

“The cost of this offer is 10 million Naira and will come out of the prize money. You have the choice to accept or decline. What will it be?” the Big Brother Naija representative told him during the call.

After a short pause, Kay Bobo responded, “Yes, I accept.”

The representative immediately congratulated him, saying, “Kay Bobo, congratulations on purchasing immunity.

“For tonight, given that other housemates are not aware of this call and the immunity that you have purchased, you must carry on as usual.

“This means, for tonight’s nomination process, you must follow all the instructions and act as though you do not have immunity.”

The reality star was further warned to keep the decision secret. “This conversation is confidential.

“You are not permitted to share with any other housemates for the rest of your stay in Big Brother’s house,” the representative cautioned.

Earlier, Kay Bobo had shown persistence in answering the call after Rooboy, the snail of the house, tried picking it but could not hear anything.

His win makes him the third confirmed finalist, following Sultana, who clinched the Head of House title, and Mensan, who was announced as the Most Influential Player earlier on Monday.

With Kay Bobo now guaranteed a spot, the battle for the remaining places in the finale is expected to intensify in the coming days. (Vanguard)
