Crazy Dave speech
(Level 1) So now you are at the top of the hill.

Pretty useful, because zombies are not good climbers.

But peashooters are still useless.

So here take this magnetic pea.

And you know why I gave you a peashooter.

BECAUSE I'M CRAZY.

(Level 5) I remember when I was 11 years old.

At that age I was the boxing champion of the elderly boxing club.

But 1 year later they discovered that I was not older than 75 years.

So they put me out of the club.

And you know why I am telling you this.

BECAUSE I'M CRAZY.

Level 5
In level 5 you need to defeat 2 waves of boxing zombies with the following plants on the conveyor belt:
 * Wall-nut
 * Cabbage pult
 * Melon pult
 * Tall-nut
 * Lillypad
 * Pumpkin
 * Squash

Area effect
Lobbed shot projectiles need more time to get down the hill.

Zombies will walk slower because they are climbing a hill.
