(Crazy Dave appears)
Crazy Dave: Do you know why my surname's Crazy? (你知道为什么我姓疯狂吗？)
Crazy Dave: Of course, because I'm crazy, for example... (当然因为我很疯狂，比如说...)
Crazy Dave: Planting on minecarts, (在矿车上种植物，)
Crazy Dave: Just like what you're doing now... (就像你现在要做的事情一样...)
This level has some tough zombie hordes but is ultimately not too hard, mostly due to the presence of Winter Melon.
Do what you need to do first, like planting Sunflowers. Delay the first few zombies via the Chili Bean and other methods.
If you want to use the Winter Melon, plant one on the first and the last lane, and another one on the middle minecart.
Keep moving the Winter Melon to extinguish the Prospector Zombies' dynamite. The Lightning Reeds will weaken the zombies. The Lightning Reeds will also neutralize the Chicken Wranglers. Use Chili Bean if necessary.
