Strategy 1-Pool Glooms
Nothing terribly original here. The strategy uses Gloom-shrooms on pool lanes, like Survival: Endless builds.

Setup:

Nothing much different from the average fog level setups, you plant Sun-shrooms, Puff-shrooms, and possibly Sea-shrooms+Imitater Sea-shrooms. You slowly replace the Puff-shrooms with plants like Fume-shrooms, but you can keep some Puff-shrooms as delayers. You plant Planterns, protect them and whatnot. You can try placing the Gloom-shrooms on the first flag, but it's preferred to do it on the second.

Post-setup:

Place Gloom-shrooms on the pool. The total cost of a pumpkined pool Gloom-shroom is 375. Then, not much else. You may add some Magnet-shrooms. You also add any plants needed to counter some zombies, like Cattails or Blovers against Balloon Zombies, Umbrella Leaves against Catapult Zombies, land Gloom-shrooms close to the left against Digger Zombies, etc.

Strategy 2- 5 Flags, 4 Cats - by EMPeachy4
Flag 1: Here's what you'll want to take:

Puff-shroom

Sun-shroom

Fume-shroom

Wall-nut

Lily Pad

Sea-shroom

Squash

Plantern

Scaredy-shroom

Cherry Bomb (If you have 10 slots)

Start out by placing Sun-shrooms on land in columns 1 and 2. Do the same with Puff-shrooms and Sea-shrooms in column 4. Do NOT plant on column 3 and do NOT place Puff-shrooms on Lily Pads. It's a waste.

After you kill the first zombie, start adding another column of Puff-shrooms and Sea-shrooms in column 5. This is also the time to start planting your Sun-shrooms in Pool columns 1 and 2, and NOW plant Scaredy-shrooms on land in column 3. Also add two more Sea-shrooms in this column. Your next job is to plant Planterns in rows 1 and 6, column 6 (You could do this slightly earlier). Plant Wall-nuts in front of them and also in front of the Sea-shrooms. The Sea-shrooms are vital to this setup. Finally, replace the Puff-shrooms with Fume-shrooms and replace the Sea-shrooms on column 3 with Scaredy-shrooms, then you are complete for the first flag! If something is going bad, use a Squash or another instakill plant. Your lawn should look like this:

S  S  SC  F  F  P  W

S  S  SC  F  F

S   S   SC   s   s   W

S   S   SC   s   s   W

S  S  SC  F  F

S  S  SC  F  F  P  W

Key: S = Sun-shroom, SC = Scaredy-shroom, F = Fume-shroom, P = Plantern, W = Wall-nut, s = Sea-shroom

NOTE: If a letter is underlined, that means the plant is on a Lily Pad.

Flag 2: These are your plants:

Lily Pad

Puff-shroom

Sun-shroom

Fume-shroom

Snow Pea

Repeater

Tall-nut

Imitater Tall-nut

Cattail

This flag is all about replacing. Right away, your Tall-nuts should be ready to be planted, so plant them on rows 2 and 4 - column 6. Your Cattail should be ready to go too, so dig up one of the Sea-shrooms on column 4, plant a Lily Pad, and then a Cattail. You should be able to have planted 2 Cattails before the huge wave, and if you're lucky you could have 3. But remember to upgrade the Lily Pads on column 4 before the ones on column 5, so they don't get eaten as quickly. You also need to remember to replace your existing Wall-nuts with Tall-nuts and Imitaters. The last thing to do is to replace the Scaredy-shrooms with Snow Peas. A word of warning, though: sun is very tight.

Your Lawn should look like this:

S  S  SP  F  F  P  T

S  S  SP  F  F  T

S   S   SP  C  s   T

S    S   SP  C  s   T

S  S  SP  F  F  T

S  S  SP  F  F  P  T

S = Sun-shroom, SP = Snow Pea, F = Fume-shroom, P = Plantern, T = Tall-nut, C = Cattail, s = Sea-shroom

Flag 3: Your Poison is... Jalapeno

Imitater Jalapeno

Lily Pad

Cherry Bomb

Pumpkin

Tall-nut

Squash

Repeater

Cattail

Upgrade the last two Lily Pads ASAP. You also need to replace your Fume-shrooms with Repeaters to deal with the Dancing Zombies! On the final wave, a Digger Zombie will come. Use a Cherry Bomb/Jalapeno as soon as you see it. Your lawn should look like this:

S  S  SP  R  R  P  T

S  S  SP  R  R  T

S   S   SP   C  C   T

S   S    SP  C  C   T

S  S  SP  R  R  T

S  S  SP  R  R  P  T

R = Repeater
