He prefers to call himself Optimus Prime.
The official name of this plant is Acidic Citrus. However, a literal translation can be found in its infobox. The official name is to be used on all pages that refer to this plant.

Acidic Citrus (强酸柠檬; pinyin: qiángsuān níngméng) is a plant in the Chinese version of Plants vs. Zombies 2. He shoots acidic lemonade droplets at zombies that do 50 damage, and any metal objects or shields on the zombies will be corroded, dealing 150 damage per shot. The damage can be increased by upgrading.



He is based on the genus Citrus limon, commonly known as a lemon. His name may refer to how lemon juice is about 5% to 6% citric acid. His ability references how acid can usually corrode metal.

The straw on his head references to lemonade, the drink that uses lemon as its ingredient.

Almanac entry

强酸柠檬 (Acidic Citrus)
Sun cost: 125

DAMAGE: Moderate



    In English:

    Acidic Citrus causes extra damage to metal armor.

    Plant feature: yellow plant

    Despite Acidic Citrus loving water, he is actually a landlubber. Honesty lights up his face whenever he discusses the days he caught the fishes underwater in his childhood. Yet, together with his current body shape and his adorable lifebuoy, that is quite unconvincing.


Plant Food effect

When fed Plant Food, he will rain lemonade droplets on the zombies three times, that does about 600 damage to all non-metalized zombies and 1800 damage to all metalized zombies on the screen. It also follows the level upgrades' special abilities, that it also do 1800 damage to Conehead Zombie and its variants when it is level 2 and 780 damage to other non-metalized zombies when it is level 3.


He will still do the same effect when plant food is placed on him, but will also acidify the water and turn the water tiles on the lawn yellow in Big Wave Beach, slowly causing damage to zombies. The yellow water fades after a while.

It is good to upgrade him to Level 4 to corrode everything, as he is one of the best plants in the game. This is due to a combination of factors, such as low sun cost, fast recharge, and it being one of few plants that are recharged at the start so he works as early defense for powerful plants like Winter Melon. When fully leveled up, however, the player needs no more plants other than Acidic Citrus for an adequate defense against zombies of any level in almost any level, as it is very powerful by itself against any zombie, even Gargantuars. In addition, the plant's sun cost can be reduced to just 100 sun, he can be planted on water, or his recharge time reduced by 30% by equipping the plant with a pendant.

  • Although his costume is an inflatable inner tube, it does not allow the Acidic Citrus to be planted on water without the aid of a Lily Pad. This trait is shared with Pea-nut, Homing Thistle, and Banana Launcher, who all have water-related costumes but cannot be planted on water.
  • He cannot turn water in Pirate Seas yellow.
  • He is the only plant that is able to change the color of the water in Big Wave Beach, making him an environment modifier. 
  • Lemonade droplets cannot extinguish Explorer Zombie's torch or Prospector Zombie's dynamite, because Acidic Citrus was not designed for those uses.
  • After the 1.4.2 update, his projectiles now deal more damage, as he now deals 50 damage to normal zombies. This means that judged by the damage difference they had before the 1.4.2 update, it should now deal 150 damage to zombies with metal armor.
    • Pre-1.4.2, his attack dealt 20 damage per shot to most zombies and 60 damage per shots to zombies with metal objects on them.
  • He appears to have a lemon slice lodged into the corner of its head, representing lemonade, a drink made with lemon, along with the straw.
  • His appearance has some features in common with the Coconut Sniper.
    • They're both open at the top.
    • They both have a straw from the opening of the top.
    • They have a decoration at the opening at the top (Acidic Citrus has a lemon wedge, while Coconut Sniper has an umbrella)
  • Acidic Citrus can damage Excavator Zombie even with its shovel on, as it corrodes metal items, but since Excavator Zombie's shovel cannot be destroyed, it only damages the zombie instead
  • He will attempt to attack Snorkel Zombies even when they are submerged, but he cannot hit them. The same applies to some straight shooting plants.
  • He and Lotuspot are the only Chinese-exclusive plants in Big Wave Beach.
  • His almanac entry references his costume.
