Banana Farm

''Generates extra money at the end of every round, but doesn't attack anything. Can upgrade to increase the money bonus.''

- BTD4 Description

The Banana Farm is the only tower that has nothing to do with actually popping bloons. This tower made its debut in BTD4, and also appears in BTD4 Expansion. The tower generates income every round, the amount depending on what upgrades you have purchased and the difficulty level. The Banana Farm itself generates 80 money per round. Its 1st upgrade More Bananas generates 120 money, its 2nd upgrade Banana Plantation generates 250 money, and its 3rd upgrade Banana Republic generates 500 money. There is a 4th upgrade that you have to unlock, called Banana Research Facility, and it generates 2000 money per round. It even gives money during Apopalypse Mode. It is generally a good idea to buy these early in the game, as you will get a bigger payoff.

Appearance
The Banana Farm is bigger than other towers, even in its first form. There is a hut on the left side of the tower, and the hut is big as a regular tower. Than there is a field to the right of the hut, colored brown. Then there is a banana tree, right in the middle of the field, looking like a coconut tree. This is what produces the money at the end of the round.

How to use

 * 1) Buy this at the beginning of the game when you can. Then around level 20, start to upgrade the farm a lot. Try to save up for Facility if you think your defenses are strong, and if you buy it it can be used to buy a sun god. This is for when your playing medium/hard.
 * 2) Buy this at level 21. Then upgrade it as quickly as you can. This will bring you a lot of money, but still don't buy the facility. This is for when your playing easy.

Trivia

 * If you are playing with Double Cash Mode enabled on Easy, you can use a Dart Monkey and build a Banana Farm before Round 1 begins.
 * In Deflation Mode, the Banana Farm is disabled.
 * However, you can still use it by pressing the Hotkey "F". They will not generate any money.
 * The Banana Farm is the only source of reliable income in Apopalypse Mode.
 * You need about 14 Banana Research Facilities to buy a Sun God every round in Easy.
