For the Monkey Knowledge Pack group, see Monkey Knowledge Packs #Bloon Sabotage.

Bloon Sabotage is the fourth upgrade of Path 2 for the Ninja Monkey in BTD6. It adds an ability that instantly slows down ALL bloons on screen (except the B.A.D) by 50% for 15 seconds, similar to the earlier Sabotage Supply Lines upgrade in Bloons Tower Defense 5. The only differences though are that Bloon Sabotage's sabotage effect cannot affect children bloons popped from MOAB-class after the start of a recent Bloon Sabotage activation but the sabotage effect can carry over rounds while duration has not yet expired.

Update History (BTD6)Edit


Nerf Bloon Sabotage price increased ($4000 → $5000).


Buff Bloons Sabotage effect can carry over rounds.



  • The Bloon Sabotage upgrade is more similar to Bloons TD Battles Mobile's version of the upgrade, due to how all bloons (including those already on the track) are slowed, unlike other versions, where the only bloons that are slowed are those that recently spawned.
  • Aside from the unupgraded Ninja, the Bloon Sabotage upgrade is the only Ninja Monkey upgrade whose artwork matches the same pose as the corresponding BTD5 upgrade.
