Bloons and Bloon Types

Made By Weird Polygon

Square Bloons
Bloons have made countless upgrades to their strategy. As a result they now have square bloons! Square bloons are quite common and appear at round 15 as blues. These things are simple, you have to use 2x the damage to pop a layer. It takes 2 hits to destroy a layer, for example. A ceramic square will have to take 20 hits to pop and a square MOAB-class bloon will take 2x the damage to pop. Bloons cannot be 2 different shape forms at once.

BTD Battles allows this type of bloon to be made at round 6 with a 1.75x cost multiplier.

BMC allows this type of bloon to be made with the Polygon Research Factory Facility. Requires 2,000 city cash and a level 12 city. 20 min. build time.

Triangle Bloons
Bloons have made lots of research. So much they've become triangles! This is like the square bloons but take 3x the popping power to pop! A red triangle would have to take the same amount of damage as a green bloon would have to to pop! However, triangles only move as fast as the bloon color they are, like other bloons. These are quite uncommon and appear at round 32 as greens. A ceramic triangle will take 30 hits to pop and a triangle MOAB-Class will take 3x the damage to pop.

BTD Battles allows this type of bloon to be made at round 13 with a 2x cost multiplier.

BMC allows this type of bloon to be made with the Angular Tri-Researcher. Requires 4,500 city cash and a level 15 city. 35 min. build time.
