Windmill

A  is a Resource Building in Bloons Monkey City which is used to generate Power, necessary for a city to run. Windmills can be built on any tile except rivers (where Watermills use instead) and lakes.

Level 1
The level 1 windmill is a brown wooden building with a straw roof and 4 wooden blades.

Level 2
The level 2 windmill is an improved version of level 1. The wood in the building has no gaps and is red-orange in colour. The roof is made of yellow wood and the blades appear to be made of cloth. It also has a door.

Resident
The Windmill, in game has no (visible) resident. However on the title screen, if the player hovers over the windmill, a monkey pops out (possibly the Monkey Farmer from BTD5 Mobile).

Trivia

 * If the player hovers their mouse over the Windmill in the title screen, a Monkey (possibly the Monkey Farmer) will pop up out of the top and shake his head. This is hard to see as the Windmill's blades sometimes block it.
 * The maximum amount of windmills the player can have in their city is 22.
 * This means if the player has all 22 windmills upgraded to tier 2, then the windmills alone will be generating 3,300!
 * In BMCm, the player can place unlimited Windmills and Watermills after city level 35, due to the fact building use more power. Ninja Kiwi said this was intentional.
