The Spy Plane in BTD4.
Spy Plane is an upgrade of the Monkey Ace tower in Bloons Tower Defense 4 and Bloons TD 5. It costs $300 on Easy, $350 on Medium, $380 on Hard and $420 on Impoppable.
Bloons TD 4
Edit
It allows nearby towers to detect Camo Bloons. Note that Monkey Aces will always be able to pop Camo Bloons, even accidentally.
Bloons TD 5Edit
This allows the Monkey Ace to hit Camo Bloons. Even though it does not aim for a target, it still needs this to pop Camo Bloons. Otherwise darts and explosives from this will not pop the Camo Bloons. Spectre and Neva-Miss Targeting will target Camo Bloons but will not pop them without Spy Plane.
TriviaEdit
- In BTD5, this upgrade does not allow camo detection for all towers.
- The Spy Plane in BTD4 looks similar the real-life SB2C Helldiver.
- In BTD5, without this upgrade, darts shot from the Monkey Ace will still be fired, but won't pop the Camo Bloons they make contact with, and will simply pass harmlessly over them.
