Freezes nearby bloons with every pulse. Frozen bloons are immune to anything sharp.
~ BTD4 Description

Ice Tower is a tower that appeared in all BTD series. It is called Ice Ball in BTD2 and BTD3. In BTD5 and all following sequels it is a monkey, but it is called Ice Tower in BTD4, BTD5 and BTDB, only in Bloons Monkey City, it is called an Ice Monkey.

It attacks by freezing the bloons for roughly half a second at first. It has a short range when not upgraded, but is still effective at delaying bloons. Without any upgrades or Specialty Buildings, it is completely ineffective against White Bloons, Zebra Bloons, and MOAB-Class Bloons.

Frozen bloons cannot be popped by sharp objects, and must be blasted or "vaporized" using a tower such as, but not limited to, the Bomb Tower, Super Monkey with Laser Vision, Monkey Apprentice's Dragon's Breath, or sunrays shot by a Sun God. Whirlwinds and tornadoes can immediately thaw frozen bloons, though they will still be blown back. MOAB-Class bloons cannot be frozen by the Ice Tower but can be damaged with the Snap Freeze upgrade.

The Ice Tower is a very useful tower because of its abilities once it has been upgraded to the Arctic Wind. In the higher rounds, it is recommended in several guides to have at least one Arctic Wind, as it can slow many bloons down to a crawl.

Differences Between BTD5 Flash and BTD5 MobileEdit

The Ice Tower has more differences between its Flash and Mobile counterparts compared to other towers.

Buff Absolute Zero ability now slows all MOAB-class Bloons on screen to half speed.

Buff Arctic Wind can slow down camo bloons if the tower is under the influence of a x/2 Monkey Village.

Buff Ice Shards and Arctic Wind can be used together.

Nerf Ice Tower's freeze effect can't hit Frozen Bloons.

Nerf When a Rainbow Bloon is popped by a 2/x Ice Tower, the Zebra children will not be frozen or affected by Permafrost. In the case of a 2/3 Ice Tower, they do not release shards. This happens even if the tower is under the influence of an x/3 Monkey Village.

Buff Snap Freeze can now damage MOAB-class bloons.

Nerf Shards of Ice Shards are now smaller than normal.

Update History (Bloons TD Battles Mobile)Edit

Ice Tower has mixed popularity. While it is often not used due to hindering towers that can't pop frozen bloons, whenever it is used the Ice Tower is most often used for its Absolute Zero upgrade, which in this game can slow down MOAB-class bloons to half speed, similarly to Sabotage Supply Lines but at a lower cost. However, the other upgrades are almost never used into popular usage, so many of the other upgrades other than Absolute Zero have been buffed through various updates. Some fairly popular load outs that use the Ice Tower are Dart Farm Ice, Apprentice Farm Ice, Ninja Village/Mortar/Farm Ice, Dartling Farm Ice, and Heli Farm Ice.

Strangely enough, the Ice Tower has received very few buffs or nerfs. While it technically has received more buffs than nerfs, the Absolute Zero nerf is more prevalent compared to its buffs that it has received.


Buff Ice Tower's freeze effect now hits Frozen Bloons, though freezing the same bloon multiple times will not stack freeze time.


Buff Viral Frost can now pop White and Zebra bloons.

Nerf Absolute Zero price increased ($2000 → $3500).


Ice Monkey

Knowledge Book in BMC

  • It is possible to stall bloons forever by putting two of these 1/1 that cover the same range, having one under the effect of Jungle Drums, or using a 1/3 Ice Tower. However this is not possible to do in the mobile versions of the games as the freeze effect cannot hit frozen bloons.
  • Along with the Monkey Ace, the Monkey Apprentice's Summon Phoenix, the Glaive Lord, the Wizard Lord, Banana Research Facility, Monkey Village, and the Monkey Buccaneer, the Ice Tower is one of the towers with an idle animation (which is the snow around it).
  • The Ice tower is the only tower in Bloons Tower Defense 5 that has its path 1 tier 4 upgrade cheaper than tier 3 upgrade.
  • In Bloons Tower Defense 4, it is the only tower that does not change its appearance at all until it is upgraded to the fourth upgrade.
  • In BTD5, the ice tower's name will not change in any way when it is upgraded.
  • The Arctic Wind upgrade is very useful in Bloontonium Lab when the tower is placed in the middle.
  • The Arctic Wind in BTD4 has a popping power of 40, so it can freeze 40 non-MOAB-Class bloons per blast.
  • Regen bloons won't regain layers while frozen.
  • You can also do Regen Farming using the Ice Tower. This has been disabled in BTD5 and BMC flash.
  • In BTD1-4, it's a non-living tower. In BTD5, however, it's a real monkey covered in snow and ice.
  • The monkey actually feels cold when it is upgraded. This is extremely noticeable with Viral Frost, when it shivers visibly on the game screen, or wearing a thick coat with Absolute Zero.
  • Viral Frost and Absolute Zero ability can freeze Camo Bloons without camo detection and pop White and Zebra Bloons (Viral Frost freezes Camos, Whites, and Zebras independently only in Bloons TD Battles Mobile).
  • If Arctic Wind is paired with a Tier 3 Ice Fortress, it can take down an insanely high number of any non-M.O.A.B. Class Bloons.
  • When a Snap Freeze Ice Tower pops the first layer of a Rainbow Bloon it will freeze Zebra Bloons, even though they cannot be frozen normally. If the frozen Zebra Bloons are popped by Sonic Boom Boomerang Thrower then the White Bloon underneath will be frozen if the tower has the Deep Freeze upgrade.
  • Ice Towers used to be used very frequently in Bloons TD Battles to make rounds last forever and give the player using them a massive income, but Ninja Kiwi changed the game so that the next round automatically begins 30 seconds after the last bloon in a round spawns, making this strategy useless. However, some people still use it but include a 2/x ice tower since this "ice-stalling" no longer makes the rounds last forever. This is called "ice shredding" by the fan base.
  • An Ice Tower upgraded to Viral Frost can be very useful against groups of Ceramic Bloons.
  • Unlike Bomb Towers, which will attempt to pop black and Zebra Bloons, Ice Towers will ignore White and Zebra bloons unless it is granted the capability of popping such bloons by use of Monkey Intelligence Bureau or Tier-3 Ice Fortress.
  • The Ice Shards upgrade for Ice Tower is similar to the Frag Bombs upgrade for Bomb Shooter.
  • The official artwork for the Ice Tower was changed in an update. The Ice Shards upgrade reuses the old artwork (with added shards to it), similar to the Monkey Apprentice, whose old official artwork is used for the Monkey Sense upgrade, the Monkey Buccaneer who's old official artwork used for the Longer Cannons upgrade and to the Banana Farm, whose old artwork is used for the More Bananas upgrade.
  • In Bloons Monkey City, it is called Ice Monkey.
  • The Ice Tower never changes its rate of fire in any of its upgrades, only its freeze length.
  • The Ice Tower will still try to freeze whites and zebras in BTD4. In BTD5, it does nothing when whites and zebras pass by it unless upgraded to Viral Frost in Bloons TD Battles Mobile, or is in the range of an x/3 Monkey Village.
  • If the Ice Tower gets either of its tier 1 upgrades purchased, the stone below it turns blue. When the tier 2 upgrades are purchased, it will have a snowflake symbol on its head.
  • The BMC artwork for Ice Monkey is similar to the BMC artwork for Monkey Apprentice.
