For the Dart Monkey upgrade in BTD5 allowing it to shoot 3 darts, see Triple Darts.
Multi Shot BTD3 Button

The upgrade button in BTD3.

Multi Shot allows the Spike-O-Pult to shoot 3 spiked balls at once. This upgrade appears in Bloons TD 3 and in Bloons TD 4 (but renamed to Triple Shot). This upgrade is not in Bloons Tower Defense 5 as it is replaced by Juggernaut. It is the last upgrade on the second path for the Spike-O-Pult in Bloons TD 3, and the last upgrade for the Dart Monkey in Bloons TD 4.

With this upgrade, Spike-O-Pults throw 3 balls at bloons at once; very deadly if purchased on earlier Rounds. It is not a good idea to rely on these too much in later Rounds as they will pop very minimal bloons due to the fact that most of them will either be Ceramic Bloons, BFBs, or MOABs.


Bloons TD 3Edit

This upgrade costs $490 on Easy, $585 on Medium, and $620 on Hard.

Bloons TD 4Edit

This upgrade costs $850 on Easy, $1000 on Medium, and $1080 on Hard.


  • In Bloons TD 3, the Spike-o-Pult had an upgrade called Juggernaut that increased the projectile size by almost 3x regular size, which also made the balls much deadlier, and they could roll much further. However, in Bloons TD 5, the upgrade Juggernaut changed the small spiked ball into a giant ball, larger than the monkey.
  • It begins as a Dart Monkey, but when it gets to Triple Shot, the monkey disappears. The monkey also disappears from the tower after the Triple Shot upgrade in Bloons TD 3 although, it can still attack, making it self-automated like the Bomb Tower and it can attack without a monkey controlling it.
  • When a Dart Monkey is upgraded to Triple Shot in Bloons TD 4, the monkey makes some final tweaks and leaves.
