Triple Barrel is the third upgrade of path 2 for the Bloonchipper in Bloons Tower Defense 5 Deluxe. It allows it to suck up Bloons three times as fast as well as sucking up three times as many bloons. It costs $3825 on Easy, $4500 on Medium, $4860 on Hard and $5400 on Impoppable. It is quite expensive compared to some of the other towers.
The Bloonchipper obtains two more barrels attached to it and each barrel becomes the color purple. Each barrel has two thin yellow stripes on them.
