Iceball

A Snowball is a giant sphere of what seems to be solid ice or snow. It is one of the Zombot's attacks used in Level 5-10 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 Snowball. After a few seconds, the Snowball 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 weak against the fire from Jalapenos.

Strategy

 * During the fight with Zombot, you can ignore this snowball, because it will not harm your brain. The only effect is, you will lose all your defence on that row. But if snowball released again in the same row, you can just ignore it. So, where 2 or more snowballs released in a row, and no zombie on the lane, just ignore and save a jalapeno.

TTrivia
The snowball is technically an iceball.

The Iceball is technically harder to destroy than a Fireball because you have to plant the Jalapeno in the same lane and because it is more tempting to use than an Ice-Shroom.
