Frag Bombs

Frag Bombs is an upgrade for the Cannon/Bomb Tower.

Upgrade description: ''When a bomb, missile, or M.O.A.B. Mauler hits a bloon, it explodes, sending out fragments. It would just explode without it.''

The Frag Bomb is a Premium Upgrade in Bloons Tower Defense 4. It made its debut in Bloons Tower Defense 3.

What it does
The Frag Bomb upgrade enables Bomb Towers to damage Black Bloons and Zebra Bloons indirectly (direct explosions will not affect it; the fragments that fly out will).

The upgrade can be unlocked when you create your MochiGames account. Unlike other items in the shop, frag bombs are free. This upgrade is helpful when you have mobs of bloons coming at you. The bombs will do extra damage.
