Fireball

A Fireball is a giant sphere of what seems to be molten metal or magma. 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.

Strategy
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 red, it will shoot a Fireball. After a few seconds, the Fireball 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 ice created by Ice-shrooms. It is easier to destroy than the Iceball, because Ice-shrooms have an unlimited range.
