Bbnaija retains ebuka show host season 3

I think there may be some confusion here!

Ebuka Obi-Uchendu has indeed been the host of Big Brother Naija (BBNaija) since its inception in 2006, but he has not been retained as the host for Season 3. In fact, Season 3 of BBNaija, also known as "Double Wahala", took place in 2018, and Ebuka has continued to host the show since then.

It's possible that you may be thinking of a different season or show. If you could provide more context or clarify what you mean by "retains Ebuka show host season 3", I'd be happy to help clarify things for you!
