Plants vs. Zombies 2/Concepts

This page contains art and concepts of Plants vs. Zombies 2. Please note that these are not fake, but rather scrapped ideas, information about upcoming plants, zombies, worlds and unreleased features. As such, some of these sections and pictures may contain spoilers.

{{LongSection|section= ==Concept art== |text=: This section shows concept art of things in Plants vs. Zombies 2.

Trivia

 * The unused flying plant resembles the Garlic Drone and Rotobaga.
 * The Miner Zombie's ability resembles the Digger Zombie's ability in the First Game.
 * The Artichoke plant resembles the Artichoke plant in Plants vs. Zombies: All Stars.
 * The Scarecrow-like zombie possibly could have crushed plants with its scarecrow. Similar to the Surfer Zombie, but it does not have the ability to surf.}}

Beet
Beet from Plants vs. Zombies Adventures was originally going to be in this game, until Bonk Choy took its place. Had it not been scrapped, it would have been the first plant from Plants vs. Zombies Adventures to be added into Plants vs. Zombies 2.

Flower Pots
The Flower Pot was seen in concept art. It was going to be used in worlds without soil, similar to the Roof in the first game, such as Dark Ages and Pirate Seas.

The pots had upgrades and had different tiers. For example, the "hover pot" would allow plants to be planted on any surface. Soon after, the concept was deemed to be too "tiring" and scrapped. A year later, this concept was picked up and put into use in Plants vs. Zombies 2 (Chinese version). Plants are now able to be upgraded via First Aid Kits.

Cleopatra Zombie
Hero Cleopatra Zombie is an unused zombie that was going to appear in Ancient Egypt. It summons 3 Mummies and this zombie is used in Plants vs. Zombies: All Stars and has the same ability. If you put her in a level, it might cause a bug that makes a level impossible to finish. There will be no zombies on screen and no reward, because of the Cleopatra Zombie not being on screen but instead off-screen where she is unreachable by almost any means.

Old Dark Ages
This version was deleted from the coding of the game as of the 2.3.1 update. It would have only sixteen levels, eight plants and ten zombies.

Old Dark Ages plants
Before the release of the 2.3.1 update, some mushrooms were found in the code. These were later replaced by the new plants in Dark Ages.
 * Pult-shroom would have lobbed projectiles at a steady rate, but slowly increasing, and lobbing more projectiles over time.
 * Vacuum-shroom would have acted like Chomper.
 * Roto-shroom would have acted like Bamboo Shoot from the Chinese version of Plants vs. Zombies 2.
 * Dart-shroom has an undiscovered effect. Before the 2.3.1 update, it was scheduled to appear in Locked and Loaded levels.
 * Scaredy-shroom would have worked exactly like in Plants vs. Zombies.
 * Zoom-shroom would have reflected back projectiles from the scrapped version of the Wizard Zombie, similar to being a plant version of the Jester Zombie from the final version.

Old Dark Ages zombies

 * Imp variants (dark_imp) - According to their names, there was going to be four imp variants: regular, conehead, buckethead and crown, rather than the final Imp Monk, Imp Dragon, and Announcer Imp.
 * Thief Zombie (dark_thief) - It could hide in darkness, becoming immune to any damage and it would steal unaware plants, you had to use a Plantern in order to see him and so he would become vulnerable to attacks.
 * This was added to the Chinese version, along with Plantern, but it no longer steals plants.
 * Knight Zombie (dark_knight) - Unlike the released Knight Zombie, it was going to have less health, approximately 21 HP and it was going to be able to deflect lobbed projectiles, similar to the Jester Zombie.
 * Barrel Zombie (pvza_barrel) - According to its code it is very similar to Pharaoh Zombie, almost the same except it has different stats. It appears to be named after the Barrel Zombie in Plants vs. Zombies Adventures.
 * Blacksmith Zombie (dark_blacksmith) - This zombie could make helmets for other Peasant Zombies, it had to first assemble approximately 5 parts of metal that would take 1.5 seconds to make and then it would make and give a helmet to the zombie that is closest to the player's house, it could also upgrade the zombies who wore these helmets. The Blacksmith was later replaced with Zombie King.
 * Gravedropper Zombie (dark_gravedropper) - Dark Ages variant of the Tomb Raiser Zombie from Ancient Egypt. It looks very similar to William Shakespeare. On Facebook, PopCap released a photo of it.
 * Wizard Zombie (wizard_zombie) - Different from the Wizard Zombie in the final game, this version would have shot projectiles at plants that would transform them into sheep. This element was reworked and combined with the beta Knight Zombie to form the Jester Zombie. The scrapped Zoom-shroom would have countered this.

The Beach (old Big Wave Beach)
This version was changed from the coding as of the 2.7.1 update. On June 20, 2014, PopCap developed the world "The Beach." The Beach would only have 20 levels like Dark Ages, however it was later changed to 25 and finally to 32 levels. All other zombies remained the same before and after the 2.7.1 update.
 * Coconut Bowler - This plant was an early version of, and was replaced by, Bowling Bulb, although its projectiles were the same.
 * Bamboom - PopCap was planning to bring a plant from Plants vs. Zombies Adventures to Plants vs. Zombies 2, as tribute to their fans due to the former game's shutdown on October 12, 2014, but the idea was later scrapped, and instead replaced by the addition of 12 more levels than the original plan. It was replaced by the Banana Launcher.
 * Banana - Unknown what this plant would have done, combined with Bamboom to create Banana Launcher.
 * Fast Swimmer Zombie - This was the only zombie that was removed in the 2.7.1 update, It does what its name suggests. It was probably replaced with the Surfer Zombie. However, it was later re-added in the 2.9.1 update.

The Beach unused content
There is also scrapped dialogue from what was originally The Beach - Day 10.
 * Preview description: "Check out the beach, it's hot. Get it? Hot!"
 * Tiki Torch-er was originally named "Coastal Calamity"

Frostbite Caves

Neon Mixtape Tour
A new world codenamed "eighties" and currently named Neon Mixtape Tour was found in version 3.8.1. The Piñata Party icons show zombies dressed in stereotypical 80s attire. Additionally, it will be split into 2 parts ("Side A" and "Side B") and it is going to be a night world. The new surprise attack is called "Punk!".

 * Neon Mixtape Tour is the first time that a world has "Side A" and "Side B" instead of "Part 1" and "Part 2."
 * This is a reference to vinyl singles in the 80s, which had 2 sides, Side A and Side B, which each had different songs on them.
 * The achievement "Beet It" is a reference to Michael Jackson's "Beat It".
 * Neon Mixtape Tour is the second world to have three words in its name, the first being Big Wave Beach.

Cactus
Cactus is a premium plant in Plants vs. Zombies 2 returning from the first game. It shoots a spike that goes through multiple zombies and it hides when zombies are close to it like a Scaredy-shroom and then deals ground damage like Spikeweed. Each spike deals 1.5 NDS piercing up to 3 zombies and the ground damage is the same as Spikeweed. The projectiles can be deflected by Jester Zombie.

Almanac entry
Sun cost: 175

DAMAGE: Normal

RANGE: Multi-Hit

RECHARGE: Fast

Cactus fires a penetrating thorn that can damage multiple enemies!

Special: hides and does ground damage when zombies are near

Things have really changed for Cactus lately. Book deals, movies, truck show appearances... she's just trying to focus on staying humble and launching thorns like always.

Plant Food
When fed with Plant Food, its spikes turn blue, its pierce is increased by 1 and its attacks become stronger for the rest of the level.

Trivia

 * It is the only plant returning from the first game with completely different abilities.
 * Although the spikes penetrates various zombies, Excavator Zombie is immune to it, as the spikes hit the shovel and continue to the next zombie.
 * Not counting with armor and plants that are supposed to be eaten, it is the second plant with a Plant Food effect that lasts until it's eaten, the other being Torchwood.
 * This, Citron, Guacodile, Strawburst, Red Stinger, and Fire Peashooter are the only projectile-shooting plants that do not shoot multiple projectiles at once when fed with Plant Food.

Beta gameplay
Before the release of the game, these are the pictures that were going to be used.

Time Twister
Time Twister was originally in the game files, but it was later removed. It would have been the final world, composed of features from all the previous worlds, or simply a prototype name for the Piñata Party.

Farm World
In the game files, there existed data for a farm world. Above there is concept art for Pitchfork, Tractor, Ladder, and Scarecrow zombies. This may have been the concept world for the earliest version of Plants vs. Zombies 2, when the game was going to take place on a farm. This may have also been an early version of Wild West.

Unused code
These are unused upgrades and text files found in the code.
 * Collectible Bacon: It is unknown what it can do, But there are some text related to "Collectible Bacon" in the files.
 * Description: Collect Bacon. Because Bacon.
 * Increase Power-Up Duration Upgrade: It can increase the duration of the power ups that are active and two exist.
 * Description: Increases the duration that your powerups are active.
 * Valuable Mowers Upgrade: It is an upgrade that can make the lawnmowers give two coins instead of one. It is found in the files.
 * Description: Drops more money for each lawnmower at the end of a level.
 * Change Vase Color Power-Up: It is a powerup that lets you change the color of one vase, for example turning a brown vase into a green vase.
 * Scrapped zombies: ZombieProto seems to be an early version of the Basic Zombie and was removed in later versions.
 * Unused zombies: There are three unused zombies named "ZombiePet", "ZombieProto" and "Cleopatra." It is unknown what Zombie Pet was going to do, since for now it just works like a slower basic zombie. (A tool named "ZombiePet" sends hypnotized zombies down the lane, as seen below.) Cleopatra summons Mummy Zombies, and stops moving as soon as it gets damaged or reaches a plant.
 * Non-colliding barricades exist, which let the player plant above them.
 * Endless Mini-games are endless versions of Mummy Memory, Cannons Away and Not OK Corral.
 * Tactical Cuke: The Cuke from the Chinese version has a seed packet in the international version named "tacticalcuke", a plant from Plants vs. Zombies: Garden Warfare.
 * Sprout was originally going to be used in the Zen Garden, instead of small plants. It was ultimately scrapped but it has codes to be plantable in-game.

Unused text

 * There is a line on the files about a message, that is shown if the player tries to plant a Tangle Kelp on a Lily Pad and other things related to Lily Pad.
 * [ADVICE_PLANT_TANGLEDKELP_ON_LILYPAD] No planting Tangled Kelp on a Lilypad.
 * [ADVICE_PLANT_LILYPAD_ON_LILYPAD] Lily pads can't be planted on lily pads.
 * [ADVICE_PLANT_MORE_LILYPADS] Try planting more lily pads!
 * [ADVICE_PLANT_LILYPADS_ON_WET] Lily pads can only be planted on wet sand and water.
 * Penny is referenced internally as "Winnie".
 * The following flavor text was scrapped:
 * Starfruit and Marigold used their flavor text from Plants vs. Zombies.
 * Citron: Since he was a young citrus he tried to donate plasma to help out people, but his juices were too acidic. Then he discovered how to donate a different kind of plasma.
 * Laser Bean: Was just a regular bean until a lab accident involving a chemical spill and a radioactive weevil gave him strange powers beyond those of normal beans.
 * Tile Turnip: Through great sacrifice comes great Power Tiles. Such is the way of the Tile Turnip.

Unused tombstones and minecarts
There are tombstones in the code for Pirate Seas, Wild West, and Far Future, and each world was originally going to have tombstones, but this was scrapped. There were also unused tombstones in Dark Ages. There are also unused minecarts and rails that were originally going to be in each world, but they were ultimately removed and they were used only in Wild West. However, in the Chinese version of Plants vs. Zombies 2, Far Future minecarts and rails are usable, as they are essential for an exclusive Brain Buster, All by Oneself, albeit with a slightly different minecart design.

Beta costs
A few of the plants had a different sun cost and gem cost prior to its final release. Some of the Power Ups were also going to have a different coin cost.
 * During the beta stages, a screenshot revealed that Melon-pult and Threepeater had the same sun costs as they did in the original game: 300 and 325 respectively. Their sun costs were switched before the final release.
 * Citron's original sun cost was 400 sun.
 * Infi-nut's original sun cost was 125 sun.
 * Bonk Choy's original sun cost was 175 sun.
 * Lightning Reed's original sun cost was 150 sun.
 * Guacodile's original sun cost was 175 sun.
 * Sap-fling's original sun cost was 250 sun.
 * All power-ups in Vasebreaker were going to cost 500 coins.
 * Power Toss' original coin cost was 400 coins.
 * Power Pinch's original coin cost was 1600 coins.
 * Power Zap's original coin cost was 1200 coins.
 * Power Flame's original coin cost was 1000 coins.
 * Ghost Pepper's original gem cost was 80 gems.
 * Fire Peashooter's original gem cost was 139 gems.

Beta music
The music that plays in Crazy Daves second transmission is the early music for Pirate Seas. It was also composed by Laura Shigihara. All this is confirmed by Laura Shigihara, as seen here.

Unused boosts
There are some unused boosts found in the code. They could be obtained in the Zen Garden. [BOOST_COMBAT_RAPID_FIRE] Faster attack rate.

[BOOST_COMBAT_SHOVEL_BOMB] Explodes when shoveled.

[BOOST_COMBAT_SUN_DISCOUNT] Reduced sun cost.

[BOOST_DETAIL_BOUNTY_HUNTER] Zombies defeated by this plant drop coins. This boost lasts for 1 level.

[BOOST_DETAIL_EXTRA_TOUGH] Extra protection from zombies. This boost lasts for 1 level.

[BOOST_DETAIL_FAST_RECHARGE] Recharges more quickly. This boost lasts for 1 level.

[BOOST_DETAIL_RAPID_FIRE] Attacks at a faster rate. This boost lasts for 1 level.

[BOOST_DETAIL_SHOVEL_BOMB] Explodes when shovelled. This boost lasts for 1 level.

[BOOST_DETAIL_SUN_DISCOUNT] Costs less sun to plant. This boost lasts for 1 level.

[BOOST_TITLE_BOUNTY_HUNTER] Bounty Hunter

[BOOST_TITLE_EXTRA_TOUGH] Extra Toughness

Plantable in-game Marigold
Marigold was originally going to be plantable in-game, but this idea was later scrapped and Marigold became only available in the Zen Garden. It is possible that Marigold will become obtainable as a normal plant in the chinese version, because in the chinese version it costs 50 Sun and is usable, and it has its levels 2-4 seed packets.

Unused costumes
Some plants were originally going to have different costumes. Some of them are used in the Chinese version or Plants vs. Zombies: All Stars, while some of them are scrapped or may appear in future updates. Most plants have unused costumes, the exceptions being:


 * Kernel-pult
 * Pea Pod
 * Jalapeno
 * Imitater
 * Hypno-shroom
 * Sun-shroom
 * Puff-shroom
 * Fume-shroom


 * Sun Bean
 * Pea-nut
 * Magnet-shroom
 * Chomper
 * Lily Pad
 * Tangle Kelp
 * Bowling Bulb
 * Homing Thistle


 * Guacodile
 * Banana Launcher
 * Sweet Potato
 * Sap-fling
 * Hurrikale
 * Hot Potato
 * Fire Peashooter


 * Lava Guava
 * Red Stinger
 * A.K.E.E.
 * Endurian
 * Toadstool
 * Stallia
 * Gold Leaf
 * Strawburst

Unused Zen Garden watering animations
The single-use plants were originally going to have boosts, thus being available in the Zen Garden. They were scrapped because since the plants disappear right after being planted, boosts for them would be completely unnecessary, although they could be saved for future updates along with the scrapped boosts. Hurrikale, Hot Potato, and Gold Leaf don't have special animations; all that happens is their normal animations restart. The Sprout from the first game was replaced by small plants.

Unused bowling ball projectile
In the Bulb Bowling Brain Buster (only in Day 8, because in Day 24 there's no code about it), there was a giant bowling ball which was going to appear (like the Giant Wall-nut in the mini-game Wall-nut Bowling 2 from Plants vs. Zombies), but was scrapped.

World-based seed packet, zombie spawner, and premium rentals
New Seed Packets were added in the 3.3.2 update. These new Seed Packets were going to be based on the world was obtained in. For instance, Chard Guard would have a Frostbite Caves seed packet, Peashooter would have a Player's House seed packet (original seed packet), etc. Other features include summoning Zombies from Lawn Mowers that would attack other zombies, and renting and trying premium plants.

Unused Leprechaun Dodo Rider
Leprechaun Dodo Rider was prepared for the 2015 St. Patrick Day's Pinata Party (Luck O’ The Zombie event) in the 3.3.2 update, but then it was scrapped. If it is spawned, the game crashes after they die. In some of the advertisements for the Pinata Party, it is shown.

Unused Pinata Party of Frostbite Caves Part 2
Its description is "Frostbite Caves is here!" and "Release the Snow Weasels!".

Favorite Plants and Recall Button
These features were added in the 3.8.1 update. Favorite Plants works as a X that when you have a plant selected and you tap the X, it gets a X on the seed packet and shows up behind the Egypt plants. The Recall Button lets you recall your last selected plants and use them. It is unknown when these features will be added.

Unused Frostbite Caves level
There is an unused Frostbite Caves Locked and Loaded level, that has all of the plants frozen in ice blocks. You start with multiple Hot Potatoes. It is named Frostbite Caves - Day 24 and would have been before the current version of Day 24.

Trivia

 * This is the only level with multiple versions of the same plant, with 5 Hot Potatoes.
 * This is also the only level where all the tiles are pre-planted on and all of them are frozen.
 * This is the only Frostbite Caves level (except Frostbite Caves - Day 30) that does not introduce slider tiles.
