Monkey Boost (BTDB2)

Monkey Boost is a boost in Bloons TD Battles 2. It adds an Overclock-like effect to all towers on screen, boosting their attack speed by around 66%. It does not stack with the Engineer's Overclock buff due to using precisely the same buff type (?). Duration lasts for 10 (?) seconds. Every game, the player starts with 3 Monkey Boosts.

Summary
Use them wisely. Use it if anticipating a defeat or any other heavy disadvantage such as losing First Blood bonus.
