3951. Cob Cannon

The Cob Cannon is an upgrade plant which can be purchased from Crazy Dave at his shop and must be planted over two side-by-side Kernel-pults, which must be placed one in front of the other in the same row, horizontally planted. Cob Cannons cost $20,000 to buy in Crazy Dave's Shop. It takes exactly 36.41 seconds to generate a new cob, It is the final plant.

The Cob Cannon costs 500 sun to place and does not fire automatically. Instead, it has a missile effect and animation. The missile itself is a corn cob which takes about 36 seconds for the Cob Cannon to load. Once it is ready, the player can click on the Cob Cannon and then use the crosshair to aim the shot. You can also right click to cancel the launch or you can click on the shovel two times to cancel the launch.The cob has a devastating effect, much like that of a Cherry Bomb, but will still require two hits to kill a Gargantuar, as all explosives do. The missile usually takes about 2-3 seconds between launching and detonating. The Cob Cannon, although highly expensive, is very effective and can dominate entire waves of Zombies very quickly, as the cobs do not use up sun between firings. Think of it as a reusable Cherry Bomb, if you don't plan to use it much, stick with the Cherry Bomb, but if you plan to use an explosive over and over again, use the Cob Cannon. The Cob Cannon is better than the Cherry Bomb in 3 ways. First, it is reusable. Second, its cob recharges faster than a Cherry Bomb. Third, it's cob can be fired on plants (including itself) and ice (without the need of a Jalapeno) or the pool (without the need of a Lily Pad), while a Cherry Bomb needs a Lily Pad for pool (flower pot for roof) use and cannot be planted on other plants (besides the Pumpkin and Flower Pot) and ice. In a few words, it is a ballistic missile in corn-cob form.
Note that the Cob Cannon can be eaten at the normal rate, despite its size, and cannot be protected with Pumpkins. Thus, they must be placed carefully. Fortunately, however, Bungee Zombies cannot target them. Be careful when clicking on sun that appears or falls over a Cob Cannon, as you may accidentally engage it. If this happens, you can cancel it either by clicking on a seed packet, pressing the Esc button or right-clicking. If you just click at a Cob Cannon thinking it may disengage, be warned as it will only shoot itself, (but not destroy itself) and wastes your patience on waiting for some Cobs that appear 36 seconds after recharging. They are good to use in almost every level.
