Explosion

Explosion is a damage type introduced in Bloons Tower Defense, and it has appeared in every Bloons game since. It is defined as the damage type of attacks unable to pop Black Bloon properties, including Zebra Bloons and DDTs. Other than those three bloon types, it can pop all bloon types. It is one of the first three damage types introduced to the series, the other two being Sharp and Metal Freeze. Bloon Wiki represents this damage type with, the upgrade icon for Bigger Bombs in Bloons TD 6, since it depicts the projectile the Bomb Shooter shoots.
