Blover

Blover is a single-use plant appearing in both main series Plants vs. Zombies games, Plants vs. Zombies: Journey to the West and Plants vs. Zombies: Great Wall Edition. It can be used to blow away airborne zombies, instantly killing them in the process.

Origins
Blover is based on the Shamrock, a young sprig of the Clover, a group of plants belonging to the genus Trifolium. Its name is a portmanteau of the words "blow" and "clover", referring to Blover's ability to generate wind to blow airborne threats away.

Blovers blow away all balloon zombies and fog.

Usage: single use, instant

Special: blows away all balloon zombies

When Blover was five he got a shiny new birthday cake. Blover made his wish, huffed and puffed, but was able to extinguish only 60% of the candles. Instead of giving up, though, he's used that early defeat as a catalyst to push himself harder ever since.

The luckiest stunt clover around, Blover is the most recent recipient of the Stunty Award. You can see his work in "Bulb Fiction," "Rooty," and "Finding Flower." He also teaches stunt class on Tuesdays at the community center.

Plants vs. Zombies
Blover is obtained by completing Level 4-3. Shortly after planting, Blover will generate a strong burst of wind by using its leaves as fans, blowing away and instantly killing all Balloon Zombies as well as repelling present fog from the screen for 15 to 20 seconds. Blover does not work against other technically flying enemies, such as Imps thrown by Gargantuars

Plants vs. Zombies 2
Blover in unlocked after beating Far Future - Day 3. Due to the improvements of the physics in Plants vs. Zombies 2, Blover is now capable of propelling all airborne enemies - this includes normally grounded zombies bounced by Spring Bean, Chard Guard, propelled by Breakdancer Zombies or dinosaurs, or flicked by Power Toss. Under normal condition, Blover can blow away the following enemies:
 * Seagull Zombie
 * Zombie Parrot
 * Jetpack Zombie and Disco Jetpack Zombie
 * Dodo Rider Zombie (flying)
 * Bug Zombie

In Far Future - Day 25, Blover can be used to stop Zombot Tomorrow-tron's charge attack. In the Chinese Dark Ages, Blover can also repel fog like in the first game. Killing 30 enemies with a single Blover will net the player the The Jettisons achievement.

Plant Food
Rollback Wind: Blover attacks all zombies on screen. It needs a Brave type of Plant Food in order for it to activate.

Plants vs. Zombies
Blover serves two primary objectives: As a defensive method against approaching Balloon Zombies, and as a tool to clear fog obstructing the player's field of vision. While each task can be done by other standing plants, Blover's relatively quick recharge rate as well as its ability to do the two aforementioned tasks at the same time makes Blover a very useful instant-use plant, especially in Fog levels.

Compared to other plants that can also shoot down incoming Balloon Zombies such as Cactus and Cattail, Blover suffers from being an instant plant and therefore requiring significantly more sun to maintain over time. On the other hand, Blover is the only plant that can defeat an undetermined amount of Balloon Zombies, and does not require a planting space that can otherwise be devoted to more powerful offensive plants. This also applies when Blover is measured against Plantern - while two Planterns only require 50 sun and can give full vision of the lawn, using Blover will save the player up to two tiles for planting more useful plants.

Whether to use Blovers or not in normal levels is mostly a matter of preference. This does not apply in Survival: Endless however, as zombie density will rapidly increase over time and Cactus and Cattail will get overwhelmed at higher flags - in this case, Blover will be the player's only effective solution. It should be noted that Blover is not invulnerable, and Gargantuars, Giga-gargantuars, Zombonis and Squash Zombies can destroy Blover like any other plant.

Plants vs. Zombies 2
As the physics engine has been updated, Blover has been made more flexible in that it can kill all airborne threats - a clever player can use this to subjugate entire hordes of zombies, including Gargantuar, with a single player. In addition, the amount of flying zombies has also been increased. Due to these reasons, Blover's significance in the player's plant arsenal has been greatly raised.

In Far Future, Blover is introduced as a counter against Jetpack Zombie and its disco counterpart, giving breathing room for other offensive plants and temporarily nullifying Disco-tron 3000's ability. Blover is also an effective plant in Pirate Seas, as most of the threats in this world such as Seagull Zombies, Swashbuckler Zombies and Zombie Parrots are naturally airborne. It is suggested that the player unlocks Blover first in the Far Future before attempting to play Pirate Seas, as Blover will make the latter world much more easy.

In Frostbite Caves, Blover is useful in defeating Dodo Rider Zombie. Blover can also be an effective plant in the Lost City, as it counters two zombies that can be otherwise dangerous without it: Bug Zombies which fly past defenses and drop zombies when defeated, especially while carrying Buckethead Adventurer Zombies, and Relic Hunter Zombies which can drop down anywhere from the fourth to the sixth column and demolish offensive plants. It should be remembered that Blover will also free trapped Lost Pilot Zombies, allow them to walk earlier than usual.

A particularly deadly combination is to use Blover in tandem with a boosted Spring Bean. As Spring Bean will render all zombies airborne for a brief period, this combination can instantly defeat all enemies on the lawn, with the only exceptions of Imp Cannon, Fisherman Zombie and Zombie King. This strategy can be used in any normal level as well as Endless Zones excluding Pyramid of Doom and Arthur's Challenge, as Blover cannot be obtained there, as long as the player has access to Power Lily or the level provides sufficient Plant Food. The main challenge in utilizing this combo is precise timing; Blover should be planted right when Spring Bean is at its highest point.

One thing to be careful about is with Blover's delay, as the wind effect only takes place when Blover starts to blow. Because of this, precise timing and plenty of practice is advised, especially when the player is attempting to kill zombies with little airborne time, such as zombies lifted by Chard Guard or Spring Bean, or Imps launched by Gargantuars or Imp Cannons.

General

 * Blover, Four-Leaf Blover, Shamrock, Shamrockstar, and Fan Blover are all based on clovers.
 * Blover and Thyme Warp are the only plants that have a "Full Board" area.

Specific to Plants vs. Zombies

 * Unlike most plants, whose out-of-combat animations have two beats (up and down or side to side movement), Blovers has three (left, middle, and right). This also happens to Gold Magnet, but much slower and shorter.

Specific to Plants vs. Zombies 2

 * Blover is not obtainable in Pyramid of Doom, Arthur's Challenge, Tiki Torch-er and Icebound Battleground, due to the lack of airborne zombies to blow (except Imps thrown by Gargantuars, zombies bounced by Spring Beans, zombies thrown from Chard Guards, and zombies tossed by Power Toss).
 * Blover is the only Far Future obtained plant that returned from the first game.
 * In its Almanac entry, Bulb Fiction is a reference to Pulp Fiction, Rooty is a parody of Rocky, and Finding Flower is a parody of Finding Nemo.
 * In the earlier updates, Blovers would instantly blow zombies away when planted. This was later changed and zombies will now only get blown off when the Blover starts turning. This has not been changed in the Chinese version.
 * In the Chinese version, it cannot be used in Castle in the Sky levels. The same applies to E.M.Peach, Bamboo Shoot, Freeze Mushroom, Sap-fling, and Hurrikale.

Specific to Plants vs. Zombies Online

 * It uses its blowing sound from the first game.
 * It is the only Far Future plant that cannot be obtained in Adventure Mode.
