Guide
Fit Farmers gives the Banana Farmer power 20% more range, from 60 to 72 units. It is a fourth-row Powers knowledge that needs 3 points in the Powers tree and Powerful Monkey Storm, plus a one-time fee of 250 Monkey Money.
It does not affect the Banana Farmer Pro power, which already has a bigger range, and it does not affect Monkey Wall Street's built-in collection.
How it changes the game
The Banana Farmer is placed like a tower and automatically collects bananas, crates and other collectables in its range, so you do not have to tap them yourself. It is mainly a convenience Power for farm strategies, especially in long games, AFK play or on mobile.
A 20% bigger radius means one Farmer can reach more Banana Farms. In practice:
- A cluster of farms that needed two Farmers might fit inside one.
- You get more freedom in where you put the Farmer, so it does not have to take the best spot near your farms.
- Bananas that fall to the edge of a farm's drop area are less likely to be missed.
It changes nothing about how much money your farms make; it only makes collecting it easier. Farms that collect their own income (Marketplaces and beyond) do not need a Farmer at all, so the knowledge matters most in the early and mid game, while your farms are still on the top or middle path and drop bananas. A common setup is one Farmer placed in the middle of four to six farms, and the extra range makes that layout much easier to fit on crowded maps.
Is it worth it?
Priority: situational. If you use Banana Farmers regularly, the extra range is welcome. Otherwise, the main reason to buy Fit Farmers is that it is the only way to Supa-Thrive and Budget Cash Drops, and through Budget Cash Drops to Grand Prix Spree.
In the fourth row, Pre-Game Prep is far more valuable. Fit Farmers comes later, when you decide to push deeper into the Powers tree.
Where it works
This knowledge only matters where both Monkey Knowledge and Powers are allowed. Powers cannot be used in CHIMPS, Races or ranked Boss Events, and challenge creators can disable them. In Contested Territory, MK is only active on regular tiles. Rogue Legends never uses MK. Banana Farmers are also not available in Contested Territory, since they have no relic there.
