Two people named Chinne and Nne, who together are called NdiNne, won the first challenge on Big Brother Naija Season 9 on Sunday night.
This was the first task for everyone in the house.
Because they won, Chinne and Nne can choose who might leave the house this week.
They also cannot be kicked out of the house this week.
Next, everyone in the house will take part in the Head of House and Immunity Challenge on Monday.
The winners of this next challenge will also be safe from leaving the house this week.
Big Brother said that there is a new rule for the Head of House challenge this season.
This year, the challenge will include drawing names from a hat.
