Rubber Harvester

"This resourceful monkey has learned to utilize the rubber from bloons as popping projectiles... terrific, I tell you!"

Rubber Harvester is a tower in BTDI that automatically collects the remains of bloons popped nearby and uses them as projectiles to attack and pop even more bloons.

When first placed, the Rubber Harvester is passive and some assistance from either another tower or a Road Item is required for it to collect ammunition and attack bloons; after that, this tower should mostly be able to supply itself on its own. Every layer of bloon popped within its radius has a 45% to add one to the tower's "ammunition count" (also called "rubber supply", counter is viewable in tower's upgrade menu, below the pop count); however, having multiple Rubber Harvesters' radii overlap over where a bloon is popped gives ammunition to only one Rubber Harvester in radius, chosen at random, and thus it is detrimental to group up excessive amounts of Rubber Harvesters in one area.

Unupgraded, its "ammunition count"/"rubber supply" caps out at 25.

Unupgraded, the rubber it shoots cannot pop frozen or Lead Bloons, and therefore letting it encounter these bloons without the necessary upgrades will most certainly drain its ammunition supply and require more assistance.
