A Fazenda 8

The teams Rabbit, Sheep and Ostrich (present on the seasons 3, 4, 6 and 7) became extinct and were replaced by two teams (Axe and Saw).

In this new season, the barn was replaced by the stall. Every week, three contestants will have to share space with the horses and sleep beside the animals.

Since season 5, contestants compete to win the Key Power each week. The Key Power holder is the only contestant who can open the mystery box located at the Farm. However, opening the box will unleash either a good consequence or a bad consequence at the nomination process.

This season, only two pre-selected contestants (one from each team) are allowed to compete each round. The winner becomes the Key Power holder for the week, while the loser is sent to the stall, along with two other contestants (one from each team) selected by the winner of the round. The Key Holder's choice is marked in bold.
