Anti-Camo Dust is a Special Item introduced in Bloons Monkey City. It allows the use of an ability that removes camo from all Bloons on screen and all bloons appearing up to 20 seconds after. It is obtained by beating a random treasure chest tile in your second city. It is a reusable item that can be used again and again in all future tiles. Activating its ability has a cooldown of 45 seconds.
This Special Item is not available in the Mobile version.
This ability also exists as a Super Rare trinket in Bloons Adventure Time TD, acting the same way as the BMC variant. It can be sharded for 300 shards.
This Special Item can be exploited by using it over and over again even when not needed every 45 seconds. Doing so can trigger Activated Ability knowledge of Ranks 3/8/13, 4/9/14 and 5/10/15 (actual triggering depends on the rank of the Activated Ability Knowledge Book).
In the game, there is a capitalization error: it reads "Anti-camo Dust" when it should read "Anti-Camo Dust" (see picture above).
When you use the ability, the screen will blink with little stars, the sound effect is like 'bling'.
There is a glitch that when you activate the ability, the screen is not blinking, but there is still the sound effect and it does not affect the gameplay as all Camo Bloons are revealed.
