Plants vs Zombies Bouncing Ball strategy is as follows:

1, first in the second and third columns planted sunflowers.

2. When the zombies appear, put a bonobo in the last column.

3. When the zombies get close, the bonobo will destroy them.

4. Then put a mimic bonobo in the last post.

5. Next, put magnetic mushrooms in the center, so that when the bouncing zombie appears you can use the mushrooms to suck away its jump bar.

6. Then put watermelon pitchers in all the first columns and block the front of the watermelons with high nuts.

7. When the zombies come out from behind, use the Doom Mushroom to blow them up, and you'll be able to successfully pass the level.
