What is zapatito big brother brasil?

As an AI language model, my training data only goes up to June 2021. I couldn't find specific information about "zapatito" in the context of Big Brother Brasil. However, I assume "zapatito" may refer to a housemate with that nickname on the show. Brazil's Big Brother, commonly known as BBB, is a reality television show based on the original Dutch version of the series. Started in 2002, the show features a group of people, known as housemates, living together in a purpose-built house for several weeks, while being constantly monitored by cameras and microphones. The housemates nominate each other for eviction, and the public votes for the eviction of their least favorite housemate until one person remains, winning a cash prize. The show has been a massive success in Brazil, with millions of viewers tuning in every week.
