Plants vs. Zombies Jumping Ball guide is as follows:
1. Plant sunflowers in the 2nd and 3rd columns first.
2. When the zombies appear, put a Japanese melon in the last column.
3. When the zombies get close, Japanese melon will destroy them.
4. Then put the imitator Japanese melon on the last post.

7. After the zombies at the back come out, use the Doomsday Mushroom to blow them up and you can successfully pass the level.
