    An Ice Tower freezing Zebra Bloons (Third upgrade of Ice Fortress)

  • Second upgrade costs Monkey Dollar750
  • Third upgrade costs Monkey Dollar1000
  • (Bloons TD 5 Mobile only) Fourth upgrade costs Monkey Dollar1250. It allows the Ice Tower to freeze camo bloons. Any bloon frozen will lose its camo status.


  • Using the third upgrade is the only way to get an unupgraded Ice Tower to freeze zebra/white bloons. Otherwise, you would have to get Absolute Zero to freeze white bloons and zebra bloons.
  • Upgrade 3 allows a 3-1 Ice Tower to solo rounds with Ceramic rushes, like 63 and 76.
  • Using the fourth upgrade is the only way to make Ice Towers freeze camo bloons without the use of Absolute Zero.


  • When you look very carefully, you can see a frozen old monkey on the left of the entrance. There is also a creature that looks like the Yeti peeking out from the right side.


  • Tier 3 Ice Fortress also allows Ice Towers to attack MOAB-Class Bloons, but not freeze them. The player could fill The Rink with Snap Freeze Ice Towers and destroy multiple BFBs.
