Grounded

Difficulty: Hard Note: This achievement is equivalent to the Nintendo DS version achievement "Unsiege Mentality".

Strategy
Fume-shroom is essential to most strategies, as it ignores the roof's angle. The best way to get it is on Level 5-1, on Quick Play. To get it, you should pick the following (Up to 8 slots). And it's a good idea to have purchased Roof Cleaners.


 * Sunflower


 * Flower Pot


 * Coffee Bean


 * Peashooter or Repeater


 * Fume-shroom


 * Umbrella Leaf


 * Garlic


 * Chomper


 * Gloom-shroom

A Garden Rake is strongly recommended.

As the achievement states, you cannot use catapult plants (Cabbage-pults, Kernel-pults, or Melon-pults, let alone Cob Cannons and Winter Melons). If you have one of them, you can't achieve this. It's not very different from any other level, so it can be easy. Start planting your Sunflowers first and then you will see a Zombie. It will step on the rake and it will die. Another one will come, so use a Peashooter or a Repeater to shoot him down. Put 4 Umbrella Leaves to defend your Sunflowers away from the bungees and later, when you have a lot of Sun, use the Gloom-shroom and Garlic, because the Gloom-shroom is technically cheaper and more efficient than a Threepeater. Then, replace the 5 Peashooters or Repeaters with Sunflowers. Then, when a Garlic is damaged, since it can't be repaired by the Wall-nut First Aid, use your Shovel and then replace them, or let them finally get eaten, but if a Flower Pot gets eaten with 1 bite after a Garlic gets eaten, put a Flower Pot on a space where a Zombie ate it, but do not be too late.

Note: This Achievement cannot be earned by completing Level 5-5 as it is a bonus level in which no achievements can be earned and this level doesn't have Lobbed-shot Plants.

Another Strategy
Replay level 5-1. Choose Sunflower, Flower Pot, Umbrella Leaf, Coffee Bean, Fume-shroom, Pumpkin, Imitater Pumpkin, Potato Mine, Squash and whatever you want (except for lobbed-shots).

First, build up Sunflowers and use Potato Mines and Squashes to save sun, until you can afford Fume-shrooms, and use Umbrella Leaves to cover every 3x3 square to protect yourself against Bungees. Use Pumpkins to protect the front Fume-shrooms from Conehead Zombies.

Fume-shroom strategy
Replay level 5-1 or 5-3. You can use this strategy on 5-6 without replay.

Choose these seeds:


 * Sunflower


 * Flower Pot


 * Fume-shroom


 * Coffee Bean


 * Squash


 * Potato Mine


 * Jalapeno

If you have more slots, use anything you want that is not Lobbed-shot. Plant a column of Sunflower. Use Squash or Potato Mine for the first few zombies. Plant 3 column of Fume-shroom and wake them up. If there are Bungee Zombie or Catapult Zombies, use Squash or Jalapeno.

Repeater/Gatling Pea strategy
This strategy is quite simple. You can try this strategy on level 5-1 whether or not you are replaying.

Pick:
 * Sunflower


 * Repeater


 * Gatling Pea


 * Potato Mine


 * Squash


 * Pumpkin

and the Garden Rake.

If replaying, also get:
 * Torchwood


 * Flower Pot


 * Umbrella Leaf


 * Potato Mine (optional, but can save you more Sun)


 * Twin Sunflower (optional, but can earn you more Sun)

Start by planting Sunflowers (aim for 2 rows, but save space for Umbrella Leaves if you have it). When the first Zombie comes, he will step on the Rake and die. When the second Zombie comes along, use a Potato Mine on him. Remember that Potato Mines take around 15 seconds (approximately 3 squares for a normal zombie) to pop out of the ground, so plant them early. When the next zombie comes along, depending on the circumstances, you may usually be able to use another Potato Mine on him. If you are playing it a second time, you can use the Imitater Potato Mine (or the Squash, but the Potato Mine is cheaper) on the zombie after that. Keep repeating this process until you find these instant kills are still recharging while zombies are coming. When that happens, plant your Repeaters. Remember to plant them on the first row behind the slanted part of the roof. Slowly upgrade your Repeaters to Gatling Peas. Also plant Torchwoods protected by Pumpkins around two to three squares in front of your Repeaters/Gatling Peas.

First time in level 5-1
It is actually possible to complete this achievement on the first time, select these plants:


 * Sunflower


 * Snow Pea/Repeater


 * Pumpkin


 * Chomper


 * Potato Mine


 * Jalapeno (for the excess of zombies on a lane)

If you got extra seed slots select other plants that could be useful. (Puff-shroom for the Bungee Zombie)

A Garden Rake is strongly recommended.

Now you have to do this formation:

S: Sunflower

C: Chomper

SP: Snow Pea


 * Protected by a Pumpkin

S S S C (SP)

S S S C (SP)

S S S C (SP)

S S S C (SP)

S S S C (SP)

Note: The third column of Sunflowers is optional.

Note: Remember to replace your Plants that have been stolen by a Bungee Zombie.

Note: Use Potato Mines to kill the Zombies at the beginning of the level to save Sun.

Note: If you decide to use this strategy on the second time through Adventure Mode, you can save your Sun supply from Bungee Zombies by replacing 2 Sunflowers with Umbrella Leaves, in rows 2 and 4.

Fumerows Method
This method is very easy to do and gains a reputation for being able to horde Sun, and possibly get the Sunny Days achievement. This is best done on 5-3, but you could do it in 5-1 too.
 * Sunflower


 * Twin Sunflower


 * Fume-shroom


 * Coffee Bean


 * Flower Pot


 * Garlic


 * Potato Mine or Squash


 * Umbrella Leaf (If doing on 5-1)


 * Wall-nut or Tall-nut (Optional)


 * Doom-shroom (Optional)

Plant 9 Sunflowers over rows 1, 3, and 5. When the first Zombie comes, Squash/Potato Mine him. Then, begin planting Fume-shrooms in rows 2 and 4, covering 1, 3, and 5 with one Garlic each. Wake up some of the Fume-shrooms, then add one more to lanes 2 and 4, and continue this until you have 8 Fume-shrooms (4 in each row) After this, the game is a cakewalk.

Note: You can get Flower Power too if you add an extra Sunflower in row 3.

Peashooter Strategy
Choose the following plants:
 * Sunflower


 * Peashooter


 * Snow Pea


 * Repeater


 * Threepeater (optional)


 * Gatling Pea


 * Jalapeno


 * Twin Sunflower (optional)


 * Pumpkin


 * Flower Pot (optional)

Fill in the rest of your empty seed slots with other useful plants that aren't lobbed shot. It is recommended to do this level on 5-1, if possible, because it is the easiest Roof level.

In the beginning of the level, plant a Sunflower in the top left corner of the screen. After enough sun has been collected, plant another Sunflower right under it. You should be able to plant one more, and if you can, go ahead. Try to plant as many Sunflowers as you can, going in all the rows, but don't go past the third column. When the first Zombie comes, plant a Peashooter in the fifth column of the roof, on the same row. Continue to do that to all of the Zombies. If a stronger Zombie comes, such as a Conehead Zombie, dig up your Peashooter in that row (if there is one), and plant a Snow Pea. The Zombies shouldn't get any stronger than that, but if you need, plant a Repeater or Gatling Pea. The largest threat will be the Bungee Zombies, but they will most likely take your Sunflowers, which are cheap and easy to replace. If a row of Zombies gets to tough for you, your fourth column should be open and you can plant a Jalapeno.

Chomper Strategy
(It is recommended to do this on level 5-1) You will need the following plants:


 * Sunflower


 * Flower Pot


 * Chomper


 * Pumpkin


 * Twin Sunflower (optional)


 * Cherry Bomb


 * Imitater Pumpkin

Besides this pick anything else you thin might help like the Umbrella Leaf, Squash, or Jalapeno (the Garden Rake is also recommended).

Fill in the first two columns with Sunflowers as you deal with Zombies with the Squash or Potato Mines. Fill in the 4th and 5th columns with Chompers as needed and plant Pumpkins over the fifth column to protect the Chompers. Since the Zombies only come about two to four at a time, you can thin them out with Squashes and Cherry Bombs while the Chompers are chewing. You can upgrade the Sunflowers if you want, replace the Pumpkins with Wall-nut First Aid and plant Umbrella Leaves in the empty column.

Fume Strategy
This strategy is very simple. You will need:
 * Fume-shroom


 * Gloom-shroom


 * Coffee Bean


 * Sunflower


 * Wall-nut


 * Flower Pot (Optional)


 * Garden Rake

Start planting your Sunflowers to the far left and by the time the 2nd Zombie comes (the 1st should be killed by the Garden Rake), plant a Fume-shroom and wake it up with a Coffee Bean. Until your Fume-shroom recharges, plant Wall-nuts on the lanes that are not protected. Once you have one Fume-shroom on every lane, make sure to plant Wall-nuts (or Tall-nuts, if you want but Wall-nuts are cheaper) to defend hem. Once that is done, upgrade your Fume-shrooms into Gloom-shrooms. '''WARNING! Do NOT plant Pumpkins on your Wall-nuts. '''The fumes from the Gloom-shrooms will not be able to hit the Zombies because the Pumpkin makes them farther away from the Gloom-shroom.

Ultimate Sun Strategy
This strategy lets you plant many Peashooting plants due to the massive amount of Sun you get from it. Best to play on Quick Play/Replaying 5-1.

Pick:


 * Sunflower


 * Twin Sunflower


 * Flower Pot


 * Snow Pea


 * Repeater


 * Tall-nut


 * Squash

It's helpful but optional to get Gatling Peas, Umbrella Leaf and Pumpkin

Start by planting Sunflowers in the Flower Pots. Once that is done or you have enough Sun, plant Repeaters in the column behind the flat surface of the roof. If Zombies come close, use Squash. After planting the Repeaters, try to upgrade them into Gatling Peas while planting Torchwood in the column in front. Plant Snow Peas in front of those and plant Tall-nuts with Pumpkins in the remaining columns. Leave the far right column empty. For the empty spaces behind the Repeaters and in front of the Sunflowers, plant more Sunflowers. Be sure to upgrade them into Twin Sunflowers. You might get the Sunny Days achievement, too.

Trivia

 * This is a reference to when an aircraft is removed from flight service.


 * This is easier on devices with Quick Play.


 * It is almost necessary to use the Pumpkin because non-lobbed plants have to be planted on the flat, right side which is too close to the Zombies (or Wall-nut if you use Squash, Chomper and/or Potato Mine only instead).
 * If you were to do this Achievement on Survival:Roof, you would only have to do the 1st Flag without Catapults in order to get it.
 * Even if you use Lobbed-shot plants on the next flag you would still earn the Achievement.
 * Playing Pogo Party without catapult plants won't get you this Achievement.
 * Probably there is a reason why Pogo Party won't let you earn this Achievement.
 * However in the iOS and Android version, you can get this achievement in Pogo Party.
