Corn cob

The Corn Cob is the projectile launched by the Cob Cannon, and it is capable of destroying a horde of zombies in an area in one shot (excluding the Gargantuar and Giga-gargantuar, which take two and four hits respectively). It is aimed manually, unlike every other projectile. The corn cob, like a usually shot short-ranged ballistic missile, is shot in the sky by a Cob Cannon and lands directly on top of the desired target. Its kill area covers a surface of a three-by-three square, like the Cherry Bomb.

Strategies
The corn cob is a projectile that is launched from a Cob Cannon. It must be recharged for 36.41 seconds, but is still very useful. The player should aim where they want it to launch, and it will kill all the zombies in the area, but take into account the amount of time between the cob being shot into the air, and when it hits, so in front of the initial target is ideal.



Trivia

 * This is the only non-automatic ammunition (excluding single use plants), and requires manual targeting.
 * It can be aimed between tiles in the PC version.
 * The corn cob is the only projectile that acts as an explosive and an instant kill.
 * The corn cob is the largest plant-fired projectile, and the third largest in the game, right after the fireball and the iceball of Dr. Zomboss's Zombot.
 * In the PlayStation Vita version of the game, a glitch occurs that does not allow corn cobs to be fired on other plants. To deal with this, the player can keep a clear square to fire corn cobs, or use the PlayStation 3 controls.
 * When aiming the cob in the PC version of the game, the player can right-click or use the Esc key to cancel the aiming.
