How do you kill the boss in Plants vs Zombies?

Answer 1

Zomboess is a tough enemy, yet easy to defeat. In the round where Zomboss will appear, there is a roulette on the top left corner of the screen. Plant as many plants as you can. Plant only Cabbagepult, Melonpult and Kernel on the pots. Save the Jalapenos and Ice-shroom for future use. When Zomboss bow his head, it's time to use Ice-shroom. It will freeze the Zombot shell and so is Zomboss. It is the right time for you plants to attack the Zombot. When Zomboss commanded his Zombot to release ball of flame, you can extinguish it by planting Ice-shroom on any planter. But if the Zombot release the ice ball, quickly trace the lane where the ball is going and plant Jalapenos there.
