Need to complete the five levels of adventure mode, and then crazy Dave will buy a batch of new goods in the store, including corn cannons, 20,000 gold coins, which are very expensive. Planting requires two corn cans and 500 sunshine. Ammunition has a loading time and cannot be used all the time. It can only be planted on the ground and on the roof, and it is not very practical except for the survival mode corn cannon. It's better to buy an ice melon, as long as 10000 gold coins have a freezing effect. It can be planted on water (with water lilies), on the ground and on the roof (with flowerpots), and its power is not small. It is a kind of plant that is easy to use, but the corn cannon is too powerful, and the zombies are gone when it is fried, but it seems that the giant zombie Ganganel, which is very awesome and huge, can't be fried at once (and the zombie Ganganel appears on the roof in adventure mode). It is better to use some ice melons, and maybe it will be killed in the case of freezing and slowing down! ! It is strongly recommended to buy ice melons before buying corn cannons! ! ! ! ! ~~
