Pea-nut

Pea-nut is an offensive and defensive premium plant that appears in Plants vs. Zombies 2. Pea-nuts can both shoot peas at zombies and block them with its hard shell. It does not shoot two peas together. Instead, each head takes turns shooting peas.

TOUGHNESS: High

RECHARGE: Mediocre

Pea-nuts can shoot peas and block zombies.

Pea-nut knows that some folks have an aversion to him. He tries to be sensitive to their concerns and give them the space they need. Still, he can't help but miss the good old days - back when he was the most popular nut around.

Overview
Pea-nut absorbs 80 bites and its appearance changes upon at 16, 32, 48, and 64 bites before being eaten at 80 bites. The Pea-nut fires slower when it reaches its third degrade. This is because both heads take turns to fire peas, so when the top head is bitten off, it shoots peas twice as slow.

Plant Food
When given Plant Food, it acts similar to Peashooter and Wall-nut, as it shoots 60 peas like Peashooter, restores its health, and gets a metal helmet, which gives it 80 more health.

Strategies
The Pea-nut can both attack and defend. Except for its mediocre recharge, it is a useful plant when you want to combine offense and defense into one plant. But pay attention to it because the Pea-nut will shoot slower when it reaches its third degrade. So if you are going to use Pea-nut as your only offensive plant, do not forget to protect them when they are weak.

Unlike in the international version, in the Chinese version they are more useful against Jester Zombie since its peanuts cannot be deflected by this zombie, so it is recommended to use it in levels where Jester Zombie appears.

Pea-nuts are great against Snorkel Zombies thanks to its great resistance, as Snorkel Zombies will be forced to eat the Pea-put while they are receiving its peas. Pea-nuts are also useful against Zombie Chickens and Ice Weasels, as they stop the Zombie Chickens and defeats them, and if paired with Lightning Reed against the Ice Weasels, Pea-nuts would make them easier to defeat.

A great strategy is planting Bonk Choys behind them and Spikerocks in front of them because the zombies will receive a lot of damage while trying to take down the Pea-nut.

Pea-nuts in Endless Zone levels infested with Gargantuars can make a great use to stall Imps. Use Pea-nuts attack and defense capabilities, but set it up in the latter parts of the level's wave, as it may trigger an immediate provoke against Gargantuars and Sandstorms (in Pyramid of Doom) if placed immediately while establishing your sun production. However, Pea-nut can only attack one Imp at a time but its mediocre recharge gives you an edge over the odds of Pea-nut being eaten alive.

Trivia

 * It was going to be a free plant in the 2.2 update's game code, but after the 2.3 update, it was listed as a premium plant.
 * It plays a different animation when its top head is gone. When it is in its second degrade, it will not move.
 * Before the 3.2 update, Pea-nut could absorb 40 bites before dying, degrading at 8, 16, 24, and 32 bites.
 * It has a slower firing rate than a normal Peashooter.
 * This, Snow Pea, Flaming Pea, Ice Queen Pea, and Fire Peashooter are the only peashooting plants that are not green. However, the Snow Pea and the Flaming Pea have a green stem.
 * Its sun cost, 150 sun, is the combination of Peashooter's sun cost and the Wall-nut's sun cost. Its recharge, mediocre, is between the recharge rates of the Peashooter and Wall-nut.
 * This and Wall-nut are currently the only plants that have three degrades, making them the plants with the highest number of degrades.
 * Wall-nut First Aid works on this plant but it will not work on this plant if it is in its second degrade. This was fixed in the 2.8 update.
 * Pea-nut along with Split Pea, Threepeater, and Pea Pod are the only peashooting plants with more than one head.
 * Pea-nut is the only peashooting plant that does not have a head that resembles a Peashooter.
 * Pea-nut, along with Pea Pod, are the only peashooting plants without a stem.
 * If one looks closely, Pea-nut's top head blinks its eyes more than the bottom head.
 * This and Chomper are the only premium plants that appear in a world's preview. It appears in the preview for Dark Ages despite not actually being obtained there.
 * Pea-nut's Almanac entry most likely is a reference to the fact that many people are allergic to peanuts, although not as many people were in the past.
 * It is the second premium plant to be purchasable before a major update, the first is the Hypno-shroom.
 * The peas are replaced with peanuts in the Chinese version (since there is no way for peanuts to form peas), so therefore it cannot be used with Torchwood, but they still cause the same green splashes as a normal pea. The green splashes have been fixed in the game, and it now has a new animation that it hits the zombie and rebounds. The hit it makes is similar to a small sun bomb explosion but is brown in color.
 * Peanuts are not actually nuts. In fact, they are rather legumes. Other legumes include beans, peas, and clovers.
 * In the Chinese version, when Pea-nut goes to second degrade it will still continue to shoot peanuts normally as if it is still intact.
 * The aversion referred in the almanac entry may refer to peanut allergies.
