1. Vigorous Cauliflower: Cauliflower will have amazing single target damage and outrageous clearing ability. Although the amplification move requires small zombies, and the planting CD is relatively long. However, the personal ultimate move can instantly kill a "giant tank" and can be called a "tank killer."

2. Peanut: Peanut is originally a very useless plant. It cannot be equipped with tree stumps for output, and it is difficult to use for defense. Not as strong as nuts. However, peanuts should not be judged by their appearance. Once peanuts are promoted to the fourth level, they will make a qualitative leap. They will not only have solid single-line output capabilities, but also have huge blood volume. Except for clowns, rugby, and archmage, no one is afraid of fourth-level peanuts. Including the new version of all zombies.

3. Bowling bubble: When you are weak, you are weak; when you are strong, you are strong. He already has a strong ability to clear the field, and when he enters the fourth level, there is no one else! Combined with ceramic tiles, an iron barrel array can be formed that is easy to defend but difficult to attack. The fourth-level bowling ball is very IMba. You can store the ultimate move in advance and wait until the zombies appear to activate it. Although it relies on random probability to activate, its planting CD is relatively short. If you don't win, you can refill it.

4. Laser Bean: The laser bean before the fourth level is simply a laser teaser, with single-target attacks for bragging rights and group attacks for damage and tickling. Once you reach the fourth level, you can obtain probabilistic special effects similar to fire gourds. Moreover, the cost is cheap and the ultimate move is practical. When the battle situation is tight, you can plant one and use it. It is super flexible! It helps you to flexibly cope with the changing environment of the new version.

5. Spore Mushroom: Launch three large spores, each causing 1800 damage, causing a new plant to grow in the cell where the zombie killed by the Spore Mushroom is. When the spore mushroom reaches the fourth level, it has a high probability of directly releasing its ultimate move. Three large spores can kill almost three zombies and grow three plants. Spore Shroom fragments appear frequently in Challenge Mode.

6. Avocado: Avocado’s ultimate move is to knock away the zombies in the front space, then vomit out two avocados, and leave with a howl. It's still very useful when encountering low-level zombies. Moreover, when the avocado plant encounters a zombie, it will push the zombie away like a cart. The cooldown time is very short, which is very good. Avocado fragments can also be exchanged for 5 fragments in the exchange shop in the battle mode for 500 gold coins.
