The Copper bloon is a bloon made of copper, hence the name. This bloon appears during Round 50, 51 and 52, but it can randomly spawn during later rounds. This bloon has 7 HP, but bombs kills it instantly. When killed, this bloon releases 1 Rainbow Bloon and 2 Zebra Bloons. The Copper bloon is immune to electricity, and if it's hit by an electricity-based attack, the bloon will regenerate all of his HP! It also attracts electricity-based attack toward him. It has a 100% chance of dropping Copper Ore, which can be sold, or kept for future use.
