Level 5 Farm Upgrade

A display for the Level 5 Banana Farm upgrade

Banana Farms are Resource Buildings in Bloons Monkey City. It produces City Cash. Each Banana Farm costs City cash2000 to build and, once construction is complete, produces City cash1 every 7.2 seconds, reaching its cap of City cash500 in one hour. Upgrading to level 2 requires rank 18 and costs City cash20000. It produces cash twice as fast (City cash1/3.6 secs) and takes an hour to reach its cap of City cash1000. This is the only resource building that will give the player towers, at 1 in-game Banana Farm for every city farm built.


The Banana Farm requires a space of 2x2 tiles. On Mobile, the Farm takes up 7x7 small tiles. Also, it seems like the 4 tiles must not include any Volcano Terrain tiles.


As of 18th August 2015 on Flash, Levels 3 to 5 of the Banana Farm are available, as well as changing the looks of the upgraded Banana Farms. The additional levels do not affect the production rate, only the maximum cash it can hold. This makes it useful if the player decides to leave the game for a while without wasting a perfect opportunity to collect a large amount of cash. Unfortunately, there is no Mobile version of Levels 3 to 5.
