Frozen Bloons grow sharp icicles that can pop Bloons that touch them.
~ In-game description

Icicles is the Tier 4 upgrade on Path 3 for the Ice Monkey in Bloons Tower Defense 6. It costs $1,700 on Easy, $2,000 on Medium, $2,160 on Hard, and $2,400 on Impoppable.

This upgrade cause Bloons frozen by the Ice Monkey to grow icicles. These icicles pop one layer off any Bloon that touches them, for up to 3 bloons. The icicles that form on bloons are considered sharp, allowing the popping of White Bloons and Zebra Bloons but not Lead Bloons.


  • Icicles is a cheap option to help control bloon rushes by dealing fair damage while freezing bloons.
  • As such, it is good to combo Icicles with a tower that deals a lot of MOAB damage but struggles against bloons, such as Arcane Spike or Dark Knight.
  • It is also a good stepping stone to the powerful Icicle Impale.
  • It is good to note that Icicles can pop White Bloons if there are other bloons it has previously applied Icicles on. This is mostly useful in player-made challenges.
