For the BTD6 counterpart, see Fireball (BTD6).

Fireball is an upgrade for the Monkey Apprentice. It appears in Bloons TD 4 and Bloons TD 5 for the Monkey Apprentice.

It returns for the Wizard Monkey in BTD6. See here for more details.

Bloons TD 4[edit | edit source]


Fireball is the second upgrade for the Monkey Apprentice and allows the Monkey Apprentice to use it as an additional projectile to choose from. Without Fireball, the Monkey Apprentice in Bloons TD 4 cannot pop Lead Bloons alone.

Bloons TD 5[edit | edit source]

Fireball is the first upgrade on Path 2; it is an additional projectile used by the Monkey Apprentice in Bloons TD 5. This new attack creates a small explosion, popping all bloons caught in it. This upgrade costs $255 on Easy, $300 on Medium and $325 on Hard. The fireball's popping power by itself is 40.

Trivia[edit | edit source]

  • In Bloons TD 5, the fireball looks like the Dreadnought Premium Upgrade when its launched by the Monkey Buccaneer, but it is simply a big fireball in Bloons TD 4.
  • The fireball can pop Black and Zebra Bloons despite exploding.
    • This is not the case for BTD5 Mobile and BMC Mobile, because the fireball explosion is more like a regular bomb explosion.
    • In BTD4, The Fireball explosion can pop all black and zebras
      • In BTD5, Only the Fireballs that directly hit the black and zebras will pop it, the explosion around it do not pop them.
  • The explosion is bigger in Bloons TD 4 than Bloons TD 5.
  • The BTD5 Artwork is closing their right eye and shows their teeth but the BMC artwork shows that they are angry and showing their teeth.
  • In BTD4, this upgrade changes its name to Monkey Mage.
