Plant Food

Plant Food is an item in Plants vs. Zombies 2: It's About Time and Plants vs. Zombies Online that gives plants more powerful effects and is obtained by killing glowing green zombies, Power Tiles in Kung-Fu World, from Tombstones in Dark Ages, spending 1000 coins to get one, or receiving one from a Power Lily, which must be purchased with real-life money. The player will find this as the level advances, they are dropped from zombies and zombies that steal plant food are glowing green and eventually shimmering green rays. The player can carry three at a time or later upgrade to four at a time (or when the player pays an in-app purchase, even upgraded to five at a time). It is represented by the lights on a bar at the bottom of the screen. Note, however, that the effect is temporary for most plants, and plants will then resume to their normal forms (this does not own the effect to Wall-nut, Tall-nut, Torchwood, Sun Bean and Hypno-shroom, which change appearance, or anything which duplicates, such as Potato Mine, Chili Bean, or their imitated forms).

Trivia

 * In the Chinese version of Plants vs. Zombies 2: It's About Time, the Plant Food is a bean instead of a leaf.
 * Plant Food somewhat resembles an atom.
 * When Plant Food is used on a damaged plant, it is restored to full health.
 * There is no reward to save Plant Food after the level ends, except in Endless Zones which the saved Plant Food can be used in next level.
 * While the plants are shining, nothing can destroy them, to the point where they are immune to shovels.
 * An exception to this is Spring Bean, which for some reason can still be killed while using Plant Food.
 * Lightning Reed also can get eaten because the invulnerability caused by plant food lasts 0.5 seconds.
 * When the Threepeater is using its Plant Food ability, the pattern the peas make resembles of a leaf.
 * If the player digs up a Chili Bean or Potato Mine that was created via Plant Food, sun will not be given if they have Shovel Boost Upgrades.
 * This may be because the player did not plant the extra Potato Mines or Chili Beans, because the Potato Mine or Chili Bean that was fed with Plant Food were the ones who created the extra.
