~ Bloons TD 6 description

Ice Monkey is a tower that has been present in the BTD series since BTD1. Originally, it was merely a ball of ice surrounded by snow, and it was known simply as Ice Tower. It was then called Ice Ball in BTD2 and BTD3, but it went back to being called Ice Tower in BTD4, BTD5, and BTDB. In BTD5, the tower was redesigned as a monkey, and has been portrayed as such in all following sequels. In Bloons Monkey City, BTD6, and BATTD, it's known as 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, Wizard Monkey'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 (exceptions in Bloons Tower Defense 6) 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. Arctic Wind also has an extra ability in BTD6 that allows you to place both land and water towers in the water affected by Arctic Wind.

As of Bloons TD 6, the Ice Monkey can now pop bloons without being upgraded, like the Snap Freeze did in previous games. However, it is more expensive in compensation, and its pierce was heavily nerfed. It now costs $425 on Easy, $500 on Medium, and $540 on Hard, and $600 on Impoppable.

Bloons TD 6[]

The Ice Tower makes a comeback in BTD6 as the Ice Monkey. The differences is that it now can pop bloons as a base tower, as if it always had Snap Freeze. However, alongside already not being able to pop White and Zebra Bloons by default, it cannot freeze or pop Lead Bloons without the Metal Freeze upgrade. Also, it no longer has infinite pierce, having only 40 pierce as a base tower. But because it can now pops bloons as a base tower, it costs $425 on Easy, $500 on Medium, $540 on Hard, and $600 on Impoppable.

Path 1 is focused mostly upon brittling the bloons, making them as vulnerable by cold as possible. Permafrost slows down bloons by 50%, thereby making them more vulnerable to other towers due to the slower speeds of affected bloons. Metal Freeze allows Leads to become affected by all attacks by the Ice Monkey. Ice Shards causes affected bloons to spawn deadly ice shards that create a chain reaction of ice shards if popped by another tower. Further Path 1 upgrades expand to increasing vulnerability of affected bloons; Embrittlement brittles affected bloons to take extra damage while frozen, while Super Brittle causes affected bloons to take even more extra damage while affected.

A super monkey placed offshore thanks to the ice monkey nearby.

Path 2 is focused more upon increasing the area effectiveness of the cold. Enhanced Freeze becomes an upgrade that both increases freeze time for affected bloons and increases attack speed of the Ice Monkey. Deep Freeze allows two layers to be soaked in cold instead of one. Arctic Wind will slow all bloons up to Ceramic down by 50%, increasing pierce while simultaneously allowing non-water towers to become placed nearby the Ice Monkey. Snowstorm increases the radial Arctic Wind effect and freeze coverage, along with an ability that freezes all bloons on screen briefly. Absolute Zero further increases the freeze range, increasing Arctic Wind effect to a 60% slow down, increasing pierce again, along with enhancing the main ability's freeze effects. When placed near water, an Ice Monkey with level 4 or above in this path allows other land-based monkeys to be placed offshore. A small ice sheet will appear underneath the monkey once placed.

Path 3 is focused more upon increasing the blast effects of the Ice Monkey. The first two upgrades, Larger Radius and Re-Freeze, focus on increasing range and allowing re-freezing of already frozen bloons, respectively. The further upgrades, Cryo Cannon, Icicles and Icicle Impale, are focused upon modifying the Ice Monkey into a projectile-based attack tower. Cryo Cannon changes the Ice Monkey to shoot iceballs instead of creating radial ice attacks. Icicles adds sharp icicles on affected bloons that act as Road Spikes. Icicle Impale allows the Ice Monkey to attack and slow MOAB-class bloons.

The Ice Monkey is a Primary class tower.

Balance Changes[]

  • Buff Super Brittle no longer makes Lead Bloons invincible for no reason.
  • Buff Ice Monkey base pierce increased (30 → 40).
  • Buff Arctic Wind main attack pierce increased (30 → 100).
  • Buff Cryo Cannon pierce increased (20 → 100).

While Icicles is quite fun for midgame cleanup, we acknowledge points raised on Cryo Cannon trading off its freeze prowess too quickly when the smaller freeze area even with such a fast rate increase still overall makes it struggle to slow as effectively. To counter this a little we have doubled the freeze radius of Cryo Cannon, but also increased damage of both the Ice Balls & Icicles to highlight more the intention of this path swapping to a damage hybrid earlier.
~ Ninja Kiwi
  • Buff x-x-3 Cryo Cannon Blast Radius increased 10 → 20. Also affects subsequent upgrades.
  • Buff x-x-3 Cryo Cannon ice ball damage increased 1 → 2. Also affects subsequent upgrades.
  • Buff x-x-4 Icicles 'shard' damage increased 1 → 2. Also affects subsequent upgrades.
Ice Monkey power is currently too bottom heavy and mid-to-higher tiers are neglected, so some tweaks to mid-tier upgrades have been made.
~ Ninja Kiwi
  • Buff Embrittlement costs less ($3,000 → $2,200).
  • Buff Arctic Wind costs less ($3,200 → $2,900).
  • Buff Cryo Cannon costs less ($2,000 → $1,750).

~ Ninja Kiwi
  • Buff Super Brittle price reduced ($30,000 → $28,000).
  • Buff Absolute Zero ability and buff duration increased (10s → 15s).
By buffing Snowstorm to have the same cooldown as Absolute Zero we unintentionally ruined a certain style of player-made challenge based on Absolute Zero timing. We have reworked the buff from v24 in order to keep the same freeze uptime but allow this type of challenge to be possible once again.
~ Ninja Kiwi
  • Buff Absolute Zero ability cooldown reduced (30s → 20s).
  • Buff [undocumented] Absolute Zero now has no initial cooldown instead of 10s initial cooldown.
  • Nerf Absolute Zero ability duration for both freeze duration and buff decreased (15s → 10s).

Damage type changes

  • Nerf [undocumented] Snowstorm ability no longer pops Lead, freeze Lead, or slows DDTs without Metal Freeze or MIB.
  • Nerf [undocumented, bug] Super Brittle no longer applies +4 damage vulnerability to bloons or blimps but can still apply Permafrost effects to all bloon types.
  • Buff [undocumented] Icicles can now apply shards onto White and Zebra Bloons but not freeze or damage them with the ice blasts.
  • Nerf [undocumented] Icicle Impale can no longer freeze DDTs without gaining lead-popping power such as Metal Freeze.
  • Buff [undocumented] Embrittlement now strips off Camo and Regrow from White and Zebra Bloons.
  • Buff [undocumented, likely a bug] Permafrost can now apply onto Whites and Zebras regardless of upgrades or external buffs.
  • Nerf [undocumented] Arctic Wind no longer slows Leads without Metal Freeze.
  • Buff [undocumented, likely a bug] Ice Shards' "shardable" status effect now affects White and Zebra Bloons. While it doesn't actually pop them, its affect still applies; causing them to release ice shards when popped by other Monkeys.
  • Nerf [undocumented, possibly a bug] Ice Shards and above now always require Re-Freeze in order to pop Frozen Bloons and therefore activate their own shards regardless of adding a nearby MIB or not. This includes Super Brittle.
  • Nerf [undocumented] Embrittlement damage decreased (2 → 1).
  • Nerf [undocumented, bug] Embrittlement no longer applies +1 damage vulnerability.
  • Nerf [undocumented] Embrittlement no longer lets Whites or Zebras frozen without MIB even if layers were skipped in doing so.
  • Buff [undocumented] 2-0-4 Icicles shards now pop Lead Bloons. Also applies for 2-0-5 Impale.

  • Change 4-x-x Embrittlement description updated to mention camo & property removal.
  • Buff 4-x-x Embrittlement once again allows 'Sharp' damage to penetrate any Bloons frozen in the Embrittled state.
  • x-3-x Placing an Arctic Wind on top of a flagship will no longer create an ice platform on top of the buccaneer.
  • Nerf x-3-x Arctic Wind no longer inconsistently slows one of two Zebra children after popping a rainbow.
  • Buff x-x-4 Icicles now correctly inherits the radius of xx3 instead of shrinking.
  • 4-x-x Embrittlement description has been updated with more detail.
  • x-3-x Arctic Wind description has been updated with more detail.
  • x-5-x Absolute Zero description has been updated with more detail.
  • 0-2-0 Deep Freeze and higher upgrades should correctly play sound again.

Differences Between BTD5 Flash and BTD5 Mobile[]

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, including Boss Bloons.
  • 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 cannot hit Frozen Bloons.
  • Nerf When a Rainbow Bloon is popped by a 2/x Ice Tower, the Zebras will not be frozen or affected by Permafrost. In the case of Ice Shards, they do not release shards.
  • Nerf The Monkey Intelligence Bureau unintentionally does not grant this tower the ability to freeze White Bloons and Zebra Bloons, but it can still pop them with Snap Freeze, effectively ruining the tower's late game viability without said upgrade.
  • Buff Snap Freeze can now damage MOAB-Class Bloons.
  • Nerf Shards of Ice Shards are now smaller than normal.
  • Buff Ice Shards will cause less lag.

Version History (Bloons TD Battles Mobile)[]

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 M.O.A.B. Class Bloons to half speed, similar to Sabotage Supply Lines but at a lower cost. However, the other upgrades are almost never as frequently used, therefore many of the 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 received.

  • Buff Ice Tower's freeze effect now hits Frozen Bloons, though freezing the same bloon multiple times will not stack freeze time.
  • Buff Juggernaut can pop frozen bloons.
  • Buff Viral Frost can now pop White and Zebra bloons.
  • Nerf Absolute Zero price increased ($2000 → $3500).

  • Nerf ...


Ice Monkeys put nearby bloons into cold storage, freezing them and popping them; especially good at corners and junctions. Powerful upgrades include: Snap Freeze, Arctic Wind, Viral Frost, Absolute Zero.

Bloons TD 6[]




  • 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 in the mobile versions of the games as the freeze effect cannot hit frozen bloons. While not the case in BTDB Mobile, round automatically continue after a certain amount of time, so it's not "forever" stalling.
  • 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 does 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, which can allow players to do Regen Farming using this tower.
  • The Ice Tower is the only tower in the series to have a major design overhaul at some point; in BTD1-4, it's seen as a big ball of ice, but in BTD5 onwards it's shown to be a monkey with cryokinetic powers.
  • 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. This does not work in BTD5 Mobile.
  • 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 made it 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 and Bloons Tower Defense 6, it is called Ice Monkey.
  • The Ice Tower never changes its rate of fire in any of its upgrades, only its freeze length.
    • This is no longer true in BTD6.
  • The Ice Tower will still try to freeze White Bloons and Zebra Bloons in BTD4. In BTD5, it does nothing when they pass by it unless upgraded to Viral Frost or supported with a Monkey Intelligence Bureau.
  • 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.
  • The BTD5-generation Flash incarnations of the Ice Monkey are the only towers in the series to have infinite pierce without upgrades.


  • In BTD6, the unupgraded Ice Monkey has less range than an unupgraded Tack Shooter, meaning it has the smallest range out of all of the towers in the game, other than towers whose radius is purely for the sake of displaying a particular tower such as the Sniper Monkey, Monkey Ace landing bases, and Heli Pilot helipads.
  • One of the Ice Monkey freeze blast sound effects is similar to one of the fruit quench sounds when slicing fruit in the game Fruit Ninja.
  • When idle, Ice Monkeys will either scratch their butt or juggle snowballs. Ice Monkeys with at least Ice Shards or Cryo Cannon have different idle animations.
