Last Stand: Fog

Last Stand: Fog is the fourth puzzle of Last Stand. The player is given 4000 sun to start with and must survive five flags.

Plants
The plants given are:
 * Lily Pad
 * Starfruit
 * Cactus
 * Snow Pea
 * Magnet-shroom
 * Pumpkin
 * Plantern
 * Cherry Bomb

Zombies
The zombies encountered are:


 * Zombie
 * Flag Zombie
 * Conehead Zombie
 * Buckethead Zombie
 * Newspaper Zombie


 * Screen Door Zombie
 * Ducky Tube Zombie
 * Jack-in-the-Box Zombie
 * Balloon Zombie
 * Digger Zombie


 * Pogo Zombie
 * Zombie Yeti (if the player has encountered it in Adventure Mode)

Strategies
The only way this strategy can go wrong is with a stray Digger Zombie or a Jack-in-the-Box Zombie explodes at an inconvenient time.

Start like this:

ECESM

ECESMP

ECEEM

ECEEM

ECESMP

ECESM

E=Empty Space

C=Cactus

S=Snow Pea

M=Magnet-shroom

P=Plantern

(italic means the plant is protected by a Pumpkin)

Add Startfruit into the empty Spaces as you progress. Due to the frequent appearance of Screen Door Zombies and you not being able to use plants that ignore the Screen Door and attack directly, Magnet-shroom is pretty much a must. Due to the column of Magnet-shroom, the chances of a Digger Zombie getting to the back and eating your plants is small. The only way this can fail is if a Digger somehow gets all the way back, or if a Jack-in-the-Box Zombie explodes and destroys the magnets. It could also fail if you don't replace the pumpkins, but that are the only times you'll need to pay attention if you're doing the strategy correctly.

Another strategy is have your lawn like this at the end:

CSS(M)(M)

CSS(M)

CSSTT

CSSTT

CSS(M)

CSS(M)(M)

C=Cactus

S=Snow Pea

T=Starfruit

M=Magnet-shroom

=Pumpkin



Start with by only using Cactus, Snow Pea and Lily Pad (optional:Magnet-shroom protected by Pumpkins).

When you get sun, then plant Starfruit and Magnet-shrooms protected by Pumpkins.

Then, you can do anything you want.

The fog is not an issue because it does not do anything and plus, this setup is pretty much going to get never beaten.

Another strategy that is very simple is:

(C)SSS(S)

(C)SSS(S)

(C)SSS(S)

(C)SSS(S)

(C)SSS(S)

(C)SSS(S)

C=Cactus

S=Starfruit

=Pumpkin

Add more Starfruit as you progress. Move the Pumpkins to the very front Starfruit in any lane.

Trivia

 * There is a possible glitch on the iPhone and Android versions where the seed selection screen is covered by fog.
 * This is the only Last Stand (Puzzle Mode) without the Pole Vaulting Zombie.
