Sell Building
The Sell building is where you turn a caught brainrot into money. The Trello card is one line - "Here you can sell your brainrots" - and it maps to the game's core money-making loop.
The community Beginner Mistakes and Money guides both stress the same rule: catching a brainrot and selling it here earns 5x more coins than killing it in the wild. That makes the Sell building the payoff step of the catch-sell loop, and the reason players are told not to kill wild brainrots outright.
Which brainrots pay best, whether there is a level requirement, and whether the price ties to rarity or level are not documented on the public sources.
