Note

After every tenth level (starts on the ninth) a zombie note is given to you. Each zombie note is badly written by a zombie telling on how they will be attacking you.

1st note
The first note is given to you after the end of level 1-9. It tells you that the zombies plan to launch an all out attack onto your lawn.

2nd note
The second note is given to you at the end of 2-9.
