Iceball

An Iceball is a giant sphere of solid ice and snow. It is one of the Zombot's attacks used in Level 5-10, the mini-game Air Raid and the mini-game Dr. Zomboss's Revenge and is released from the Zombot's mouth.

Overview
During the mini-game, the Zombot may move its head down to pick a lane on which to place the projectile. If the Zombot's eyes turn blue, it will shoot a Iceball. After a few seconds, the Iceball will roll down the lane plants and squish every plant it touches until it is destroyed or it rolls off the end of the lane; it will also crush any roof cleaners in the row. It is destroyed when hit by the fire from Jalapenos.

The only differences between these and the ones in Level 5-10 or Air Raid is that it flies, immune to Jalapeno and sometimes contains a plant, such as a Pumpkin or a Jalapeno.

Strategies

 * See Dr. Zomboss for more strategies.

During the fight with Zombot, you can ignore this iceball, because it will not harm your brain. The only effect is that you will lose all your defense on that row. Even your Flower Pots will get flattened. But if an iceball is released again in the same row, you can just ignore it. So, where two or more iceballs released in a row, and no zombie on the lane, just ignore and save a Jalapeno. In Air Raid, these are frequently released from the Zombot's mouth. The iceball is technically harder to destroy than a fireball because the player has to plant the Jalapeno in the same lane and because it is more tempting to use than an Ice-shroom. The player can also plant the Jalapeno in the wrong row, while the Ice-shroom affects the entire screen.

Trivia

 * The iceball in the Nintendo DS mini-game Air Raid has an iceball that looks more like a bubble than a normal iceball released from the Zombot's mouth.
