Doom Cannon: Cob Cannon that shoots black cobs that kill zombies in a 5x5 square around it (like a Doom Shroom) It looks just like a Cob Cannon, but like I said, the cob is black. It is still the upgrade of the Kernel Pult, and needs to be planted on 2 side by side Kernel Pults. It costs 800 sun, and with the cost of the Kernels, it has a total cost of 1000 Sun. It would cost $80,000 in Crazy Dave's shop, and can only be bought after beating all the minigames and get 10 achievements.
