The Cannon is a tower in Bloons Tower Defense 3 and its ports. It attacks by shooting bombs that explode on contact with the first Bloon, creating an explosion that has 18 pierce. Its attack speed is slow and it cannot pop Black Bloons, but it can pop Lead Bloons. Its upgrades increase its blast radius, range, pierce, projectile speed, attack speed, and cause its bombs to release frags that can pop more Bloons.
