Snap Freeze



Snap Freeze is an upgrade for the Ice Tower that was introduced in Bloons Tower Defense 3. When a bloon gets hit by the Ice Tower/Ball, it will pop a layer of that bloon and then freeze the layer below in the process. In BTD4, it appears as the regular ice tower, except with 3 Upgrade Marks by the side.

Trivia

 * This upgrade allows for the only (other) way to freeze a Zebra Bloon. If the player hits a Rainbow Bloon with an Ice Tower with Snap Freeze, it will pop the Rainbow Bloon and out will come a frozen Zebra Bloon.
 * It is impossible to freeze an White Bloon, unless you use tier 3 Ice Fortress, though it is possible to freeze a Zebra Bloon by the above method.
 * With this upgrade, it is impossible to freeze a Pink Bloon unless a Black Bloon is frozen and popped.
 * This is the only upgrade for the Ice Tower that can pop Bloons.
 * It was possible to freeze a White bloon in BTD3 by popping a rainbow bloon.
