The Brazil Cube, also called BR Cube, is a cube covered with the Brazilian flag on each of its faces. It's an easter egg hidden in 
Don Swan's 
Mansion, next to the 
Thailand Ball, and it has no utility today other than decoration. Its reputation comes from a version summoned by admins, which once offered a free 
Dark Blade.
How to get it
It is located inside Don Swan's Mansion, in the 
Second Sea, right next to the Thailand Ball.
The detail to spot
- The words "Que Isso" are written on the cube. In Portuguese, it means "What is this?".
- The Fandom sees it as a wink from the developers to Brazilian
Blox Fruits players.
The free Dark Blade story
- The Brazil Cube could once be summoned by admins. When you touched it, you were teleported into a maze, and completing it gave you a free Dark Blade.
- It only works with a cube summoned by an admin: the one in the Mansion is purely decorative.
- According to the Fandom, not all admins know how to use it. The only one known to be capable of it today is
rip_indra. - OfficialNoobie, a Blox Fruits YouTuber, is among the rare people known to have received a Dark Blade from a Brazil Cube summoned by rip_indra.
