Flash Bomb

"Sometimes throws a flash bomb that stuns bombs in a large radius."

- In-game description

This is the third upgrade of path 2 for the Ninja Monkey. It costs $2340 (Easy), $2750 (Med), $2970 (Hard). It can stun and pop up to 60 bloons. This upgrade is not recommended for popping camo lead bloons, unless it's the only way on a daily challenge, due to the cheaper cost of the Monkey Apprentice, and it's faster firing speed. It turns the ninja dark blue with a red bandana.

Trivia

 * This is the only upgrade for the Ninja Monkey that can allow it to pop Lead Bloons.
 * For around every 3 Shurikens that the Ninja Monkey has thrown, a Flash Bomb is thrown.
 * It is equally expensive as the Bloonjitsu Master (however, Bloonjitsu Master requires buying Double Shot) yet not as effective in general. However, one could argue that its ability to pop Lead Bloons makes it slightly more useful.
 * It's more expensive than his fourth upgrade, Sabotage Supply Lines, which costs $1800
 * In mobile versions, the bomb is larger than the computer version.
 * The Flash Bomb is useful for popping camo leads.
 * This makes the Flash Bomb especially useful in BTD Battles,as the opponent can send in camo leads on Round 12 (of course,that's just for starters. Other upgrades cost a lot less.)
