Crow's Nest



 is an upgrade for the Monkey Buccaneer in Bloons Tower Defense 4 and Bloons Tower Defense 5

This upgrade "Allows detection of camo bloons for any tower in the radius". It is good for those early rounds with Camo Bloons if you don't have any other tower or upgrade that is able to detect them. In Bloons TD 5, this upgrade only allows the Monkey Buccaneer to detect Camo Bloons.

Bloons Tower Defense 5
In Bloons TD 5, this upgrade is the 2nd upgrade of path 2 for the Monkey Buccaneer. It costs $210 on Easy, $250 on Medium, and $270 on Hard.

Trivia
In BTD5 this upgrade does not allow camo detection for all towers.
