Survival: Pool

Survival: Pool is the third level of Survival Mode.

Zombies
Only Zombie, Flag Zombie, Conehead Zombie, Buckethead Zombie and Ducky Tube Zombie must appear every time.
 * Zombie
 * Flag Zombie
 * Conehead Zombie
 * Pole Vaulting Zombie
 * Buckethead Zombie
 * Newspaper Zombie
 * Screen Door Zombie
 * Football Zombie
 * Dancing Zombie
 * Backup Dancer
 * Ducky Tube Zombie
 * Snorkel Zombie

Strategy 1: Fire Pea Gold Magnet
This is a strategy that is moderately hard to set up but pays off by letting the rounds play themselves and still not lose any money.

Plants:
 * Sunflower
 * Repeater
 * Gatling Pea
 * Torchwood
 * Pumpkin
 * Magnet-shroom
 * Gold Magnet
 * Lily Pad
 * Potato Mine
 * Pumpkin
 * Emergency Instants
 * Filler

Optional:
 * Imitater (Pumpkin)/(Potato Mine)
 * Marigold

Setup:

Start by planting your Sunflowers, as usual. When a zombie appears, use a Potato Mine. When you can afford them, plant Repeaters, their alignment being in a column. Put Torchwoods in front, and upgrade to Gatling Peas when you can (sooner is better). Place the Gold Magnets as seen in the picture(in front of torchwoods, inner land row). Now Pumpkin all the Gold Magnets and Torchwoods. At this point, you can leave and do anything else, as the round will pretty much play itself as long as the game is running. Optionally you can add Marigolds to receive some more money. Note that, from testing, it's impossible to do the whole setup in a single flag.

Jackninja5's Strategy
Step 1:

Plants needed:

Sunflower Do what you did at the first flag of Survival: Day with Lily Pads but use Potato Mine for the first zombie. If you have enough time plant Twin Sunflowers on the Sunflowers. Use Tangle Kelp when the ambush zombies get out of the water. Yes I have a diagram:
 * Peashooter
 * Lily Pad
 * Snow Pea
 * Squash
 * Potato Mine
 * Tangle Kelp
 * Repeater (optional)
 * Gatling Pea (optional)
 * Twin Sunflower (optional)

S S P SP

LS LS LP LSP

L = Lily Pad, S = Sunflower, P = Peashooter, SP = Snow Pea.

Step 2:

You must choose:


 * Twin Sunflower


 * Repeater


 * Gatling Pea


 * Tall-nut (I don’t trust Dolphin Riders but use them on ground too)


 * Lily Pad


 * Tangle Kelp (keep drowning the closest ambushes)


 * Torchwood (if you want)


 * Jalapeno (optional)


 * Squash (optional)


 * Cherry Bomb (optional)


 * Wall-nut (optional)

Last daytime level (Day and Pool are both in the day) I used a fire killing spree. Use a fire one if you want, but I am using an ice killing spree. I hate the cold but I want it to be unique. So replace Peashooters with Repeaters and use the Tall-nuts. Twin Sunflowers. Remember them? Do that Twin Sunflower thing again. You can do the Gatling Pea thing again too. And the diagram is now:

NOTE: R’s and GP’s! Put the GP’s on any R’s you want! TN’s go wherever you want too! I will show you what I did! Whatever you do, no difference!

S S R SP

S S R SP TN

GP = Gatling Pea, TN = Tall-nut, R = Repeater. If you are using the fire killing spree, replace the SP with TW (Torchwood)!

Step Number 3:

Choose these:

Twin Sunflowers! Gatling Peas! Tall-nuts! Keep using them! Tangle Kelp never change! Here is the diagram: TS TS GP SP TN
 * Twin Sunflower
 * Gatling Pea
 * Lily Pad
 * Tall-nut
 * Tangle Kelp
 * Squash
 * Coffee Bean and Doom-shroom (both optional; probably for a bomb as the Gatling Peas are like war soldiers)
 * Jalapeno (optional)
 * Cherry Bomb (optional)

If you are using the fire killing spree, replace the SP with TW!

Step 4:

Football Zombies and Dancers are here! Choose:

Don't worry about the Football Zombies! They will die by Gatling Peas and go slow! Keep the Twin Sunflower strategy up! Tangle Kelps; still use them! Tall-nuts should be with you when your Tall-nuts are damaged.
 * Twin Sunflower
 * Lily Pad
 * Tall-nut (replace damaged ones)
 * Tangle Kelp
 * Any plant

Final and Last Step:

Choose the plants:

Just do the same thing again!
 * Twin Sunflower
 * Lily Pad
 * Tall-nut
 * Tangle Kelp
 * Any plant

Buttered Wintermelons
By BGB64

Plants

 * Sunflower
 * Potato Mine (Optional)
 * Kernel Pult
 * Melon Pult
 * Lily Pad
 * Cattail (Optional)
 * Tall Nut
 * Winter Melon (Optional)

Strategy
Plant a column of sunflowers at the furthest to the left, while using potato mines (if you picked them) or beginning to plant a column of kernel pults in the second column. If you picked twin sunflowers, plant them ASAP. Plant the tall nuts in the fourth column from the right, only in the pool. Plant a column of melon pults in front of the kernel pults, and slowly upgrade them to winter melons. In the pool between the melon pults/winter melons and the tall nuts plant the cattails.
