Introducing you all to the BRB: The BIG... ROTATING... BUILDING!!!

The Big Rotating Building (BRB) is where Four and X have sent the eliminated contestants after the events of "X Marks the Spot". It was first mentioned in "Take the Tower" and first seen in "Who Stole Donut's Diary?".


BRB looks similar to the Yoyle Needy and is blue and white. There are cages attached to it and a small opening and closing door that reveals gears. There is also a banner which says "Big Rotating Building". It has 2 open doors, exposing the gears.

Contestants that have entered the BRB

The contestants are listed in order of elimination.


  • Similar to the Tiny Loser Chamber and Locker of Losers, BRB shares an acronym for a well-known phrase, "be right back".
    • This was further hinted in "A Taste of Space", when Four stated "The contestant with the fewest votes will BRB".
  • Balloony, Spongy, and Ruby were heard screaming and Loser was mentally scarred when eliminated and made weird sounds at the end of the stinger.
  • Before the release of "Who Stole Donut's Diary?", the function of the BRB was accidentally mentioned in the Humany video "BFB 21 Behind the scenes of X's lines (done by cary)", Cary mentioned Ruby was being spun in the BRB. This was later edited to have the video cut off at the "spinning around part", but this confirmed that Ruby, along with the other BRB prisoners, were being spun around.
  • The cages in the BRB are a possible reference to the cage that Firey was locked up by Book in Welcome Back.
  • In the Humany video "CARY REACTS TO BFB 22", Cary says that the BRB's model was based on the Yoyle Needy.
  • As of "Who Stole Donut's Diary?", Taco is the only eliminated contestant not heard screaming.
  • As of "X Marks the Spot", at the end of every episode, screaming is heard from the BRB.
