Black Bloon

"Black Bloons are nasty - they are small but they contain 2 yellows inside them. Oh did I mention they are IMMUNE TO BOMBS?!"

- Round 26 in Bloons Tower Defense 1

The Black Bloon is a parent of the Pink Bloon in Bloons Tower Defense 4 and in Bloons Tower Defense 5. In other Bloons Tower Defense games, the Black Bloon is a parent of the Yellow Bloon. The Black Bloon has a powerful anti-bomb shell that is immune to bombs, mortars and pineapples and usually appears around rounds 20-25. It spawns 2 Pink or 2 Yellow Bloons (before BTD4) when popped. When it and its descendants are popped in BTD4, it yields a total of 11 money. When it and its descendants are popped in BTD1-3, it yields a total of 9 money. The Black Bloon is also in every Bloons TD game to date.

Trivia

 * In BTD5, Black Bloons can be popped by using the bloon buster upgrade for the mortar tower when it is attacking a lead bloon, the big one on a rainbow bloon or burny stuff. In BTD4, Black Bloons can be popped by Bomb Towers if they are upgraded with frag bombs. Same with in BTD3. However, 1 layer is popped rather than 2.
 * Note that Mortar Towers cannot pop black bloons, except through either the method above, by the Mortar tower's Burny Stuff, if they are within range of the Monkey Intelligence Bureau (works for all towers) or if the tower has the upgrade The Big One.
 * It is sometimes confused with the Bomb Bloon. Both deal with bombs.
 * In BTD and BTD2, because of it's resistance to bombs, you can't beat the game with only Bomb Towers. In BTD3, BTD4, and BTD5 it is possible because of the Frag Bombs upgrade and the Bloon Impact upgrade (BTD5 only)
 * Road Spikes may work in BTD2 but it is still difficult, especially on Hard.
 * Black Bloons are slower than white bloons.
 * They appear in every Bloons TD game to date.
 * They have the exact speed of a green bloon.
 * It is strange how a black (and whites) bloon is small yet contains larger pink bloons.
 * Black bloons are encountered earlier than White bloons.
 * If you upgrade the Frag Bomb Tower to a Cluster Bomb Tower, the tower will not be able to pop black bloons anymore until upgraded to Bloon Impact
 * White Bloons move faster than Black Bloons.
