Costume-Shroom

Costume-Shroom is a plant that may or may not exist in Plants Vs. Zombies Impersonation. When initially placed on the lawn, Costume-Shroom dons a mask that resembles the head of a regular zombie; thus, in its initial state, the Costume-Shroom cannot be eaten or otherwise destroyed by most zombies, and zombies that ignore it just pass by it. After a zombie passes by Costume-Shroom, the plant hides under its cap for around 5 to 6 seconds in a similar manner as a Scaredy-Shroom and then uplifts its cap to reveal itself with a specific mask, outfit, or otherwise appearance that gives it a distinct ability or function, depending on what type of zombie had passed by the Costume-Shroom.

Costume-Shroom, being, to some extent, a "magical" mushroom, is a plant of both the Enchant-Mint family and the Amass-Mint family, as the game he supposedly appears in allows plants to have dual plant families.

Origins
Costume-Shroom's ​​name refers to both how it attains the respective costume of a zombie that passes by it and how most of the mushroom plants in the Plants Vs. Zombies series end in "-Shroom". Costume-Shroom's name is also inspired by how many mushroom plants often have an "-ume" or "-oom" rhyme before the suffix of "-Shroom" (i.e. Fume-Shroom, Perfume-Shroom, Doom-Shroom, Gloom-Shroom).

Plant Food Effect
When fed Plant Food, Costume-Shroom WIP

Enchant-Mint Effect
Costume-Shroom's abilities have double the effectivity, depending on what they are (e.g. a conehead costume's main function is defense, therefore, Costume-Shroom gains double health, whilst Costume-Shroom gains double damage for a shockwave costume, or Costume-Shroom blows away zombies twice, etc.).

Amass-Mint Effect
Costume-Shroom's abilities have double the effectivity, depending on what they are (e.g. a conehead costume's main function is defense, therefore, Costume-Shroom gains double health, whilst Costume-Shroom gains double damage for a shockwave costume, or Costume-Shroom blows away zombies twice, etc.).

Level Upgrade
Shiverpeace doesn't believe in the level system in PvZ2 that made plants completely broken and arguably very overpowered, cashed in on players spending money on coins and seed packets, and also strayed off of what Shiverpeace believes what was one of the most fundamental parts of the main Plants vs. Zombies series; that the game series was too simple to have this kind of scaled, definitive leveling up system of individual plants that additionally made PvZ2 even more P2W than it was before (speaking of this, maybe Shiverpeace should nerf the Power Mints a bit).

Strategies
This plant changes its entire ability and/or function to your favor depending on what zombie passes by, proving itself to be very versatile in many different situations. Often times, the Costume-Shroom obtains abilities or attacks that effectively counteract or are otherwise helpful against the zombie Note: The Costume-Shroom is not ignored by Explorer Zombies or Torchlight Zombies and will be destroyed by them upon contact. Same goes for Barrel Roller Zombies, Piano Zombies,
 * If a Basic Zombie, Imp, Flag Zombie, or any of the three zombies' respective variants or pass by, the Costume-Shroom ignores it, does nothing, and awaits the next zombie.
 * If a Conehead Zombie or any of its variants pass by, the Costume-Shroom attains a cone on its head that increases its health to that of a Wall-Nut.
 * If a Buckethead Zombie or any of its variants pass by, the Costume-Shroom attains a bucket on its head that increases its health to 133% of that of a Wall-Nut.
 * If a Knight Zombie, Blockhead Zombie, or Jurassic Fossilhead passes by, the Costume-Shroom attains an army commander's helmet on its head that increases its health to 167% of that of a Wall-Nut.
 * If a Brickhead Zombie or any of its variants pass by, the Costume-Shroom attains a bricked chimney-like headpiece that increases its health to that of a Tall-Nut.
 * If a Ra Zombie passes by, the Costume-Shroom attains a hat similar to that of the Ra Zombie's and the plant gains the ability to instantly produce 300 sun upon being eaten.
 * If a Camel Zombie or a Tomb Raiser Zombie passes by, the Costume-Shroom attains a "hat" similar to that of the Battle-Mint and the plant gains the ability to release a heavy-damaging shockwave down the lane upon being confronted by a zombie.
 * Flying zombies such as Seagull Zombie, Pelican Zombie, Jetpack Zombie, Blastronaut Zombie, and Bug Zombie that pass by will make the Costume-Shroom attain a hat in the image of a Blover, gaining the ability to blow away all flying or floating zombies upon being confronted by a zombie. The Costume-Shroom disappears after fulfilling its effect.

Trivia

 * This plant was created for the 2019 Lawn of Doom Contest.
 * The Costume-Shroom "tailors" itself to your favor, in both ways (tailor as in "adapting" to the player's needs and literally costume tailoring).
