Stealthy tower that can see Camo Bloons and throws sharp shurikens rapidly
~ Official tower description
Gotta love all things ninja.
~ Bloons TD 5's Big Bloon Sabotage Description
Stealthy and fast Monkey that throws bladed shurikens to pop the Bloons. Can target Camo Bloons.
~ Bloons TD 6 description

Ninja Monkey is a relatively fast, moderately damaging, Camo detecting monkey tower that can be downright fatal to many bloons if used correctly. This tower made its debut in Bloons TD 5 and makes appearances in Bloons TD 5 Deluxe and other portable versions of Bloons TD 5. It also is in Bloons Monkey City and Bloons TD Battles. In BTD5, its Specialty Building is named the Ninja Academy, and in BMC, it has an upgrade building that is named the Ninja Dojo.

A 0/0 Ninja Monkey may be worth its cost, acting like a 1/1 Dart Monkey except it fires slightly faster and is a little more expensive than it as well as providing cheap Camo detection. On its own, Lead popping power can be quite a nuisance to get up early as the x/3, the only upgrade that allows the Ninja Monkey to pop leads, costs a hefty $2750 on medium. It is good to have a 0/1 Bomb Tower or a Monkey Apprentice which costs less and works very well with Ninjas. As for the last few upgrades on either path, they both help the Ninja stall bloons for other towers to pop them. A 4/2 Ninja has a very large distraction chance (Though still not 100%) and a 2/4 Ninja has its ability to slow down bloons, a flash bomb to stun bloons as well as the usual Distraction upgrade to send bloons back to the start.

Bloons TD 6[]

The Ninja Monkey makes a return in BTD6, and it attacks similarly to how it did in BTD5. It pops two bloons per shot at a speed faster than the unupgraded Dart Monkey, as well as always detecting Camo regardless of upgrades. Compared to BTD5, the Ninja Monkey now also can be upgraded to various upgrades that specifically remove Camo status from bloons, upgrades that enhance other Ninjas in its radius, and upgrades specifically damage MOAB-class bloons heavily. It can be upgraded to be Anti-MOAB, to be able to unleash a river of deadly shurikens or be able to heavily reduce the impact of incoming bloons.

The Ninja Monkey is classed as a Magic Monkey.

Differences Between BTD5 Flash and BTD5 Mobile[]

  • Buff Flash Bomb has more contact area, as the stun grenade instead appears as a Bigger Blasts bomb.
  • Nerf After the Sabotage Supply Lines ability wears off, the affected bloons will recover and once again move at full speed.
  • Nerf Shuriken hitbox is smaller.
  • Nerf Seeking Shuriken homing targetting area decreased, making shurikens less able to detect backwards targets.
  • Nerf Shadow Double Ability (from Ninja Academy Specialty Building) now only creates a 0/0 regardless of upgrades of any Ninja.

Update History (Bloons TD Battles Mobile)[]

The Ninja Monkey is a pretty popular tower. With its versatility, it is able to counter most early-game bloons pretty well, as well as being all-round Camo-detectors. In particular, the Sabotage Supply Lines ability is still popular among the late-game, where sent MOAB-class bloons can be a pain for many towers, where slowing them would be of great help. On the other side, Bloonjitsu is a very popular all-round popper (except Leads of course), and spamming them can often defeat most bloon rushes.

Popular strategies for the Ninja Monkey include the Ninja-Mortar strategy, the Ninja-Bomb strategy, the Ninja-Apprentice (this one is especially so among newer players), and Ninja-Boomerang strategy. The most powerful combination currently is the Ninja-Mortar, which can become almost unstoppable until Round 18 if played correctly, while also being a good counter to the COBRA.

The Ninja in general is overall nerfed in terms of cost, with Sabotage Supply Lines becoming directly more expensive than in other games. (The overall cost to get a 4/x Ninja used to be cheaper compared to BTD5 but after 4.9 it's now the same.)

  • Buff x-x-5 Master Bomber price reduced from $60,000 → $40,000.

12.0

21.0
While Sticky Bomb still has issues we are investigating, this damage buff allows Sticky Bombs to destroy all regular MOABs from round 81 to 100 in a single bomb in standard games whether they are fortified or not. In addition since this damage runs off a timed function, somewhat similar to Alchemist's Unstable Concoction, we felt that adding a range increase to the Sticky attack similar to Concoction should give a better chance to actually explode before the target MOAB is destroyed by other towers.
~ Ninja Kiwi
  • Buff x-x-4 Sticky Bomb damage increased from 400 to 500.
  • Buff x-x-4 Sticky Bomb 'sticky attack' range increased to Ninja's range * 1.5.
25.0
Ninja's Bloon Sabotage is often used in tricky rounds as a powerful slow with a long duration, so we have made a gentle price increase here to reflect that support strength.
~ Ninja Kiwi
  • Nerf Bloon Sabotage price increased from $5,000 → $5,200.
