A Tack Bloon is a Pink Bloon with a tack symbol on it. When popped, it shoots a volley of tacks in 8 directions. It was featured in the level Surprise (Bloons Pop 1); Right n Left in Bloons 2. However, the tack symbol shimmers over time in Bloons 2. In Bloons 2 Christmas Pack, it is a mistletoe, and shoots mistletoe instead of tacks. And in Bloons 2 Spring Fling, it is a rose. Each tack can only pop one Bloon.
This Bloon is commonly used in 'Chain-Reaction' levels made by the community, as if a tack from the Bloon hits another Bloon, it activates it's abilities and so on and so on. It is also good for getting into tricky places that darts thrown by the monkey cannot reach.
|The term "Prickly Bloon" is only a popular term coined by fans and has not been confirmed by official sources.|
