Pea-nut

Pea-nut is a premium plant in Plants vs. Zombies 2: It's About Time. 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.

Overview
The Pea-nut absorbs 36 bites and its appearance changes upon at 7, 14, 21, 28 bites before being eaten at 36 bites. The Pea-nut fires slower when it reaches its third degrade.
 * This may be because both heads take turns to fire peas, so when the top head is bitten off, he shoots peas twice as slow.

Plant Food Upgrade
It is similar to both the Peashooter and the Wall-nut, as it both shoots 60 peas like Peashooter, restores its health and gives itself a hard helmet which lets it resist 72 more bites.

Almanac Entry
Sun Cost: 150

DAMAGE: Normal

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.

Strategies
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, 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, don't forget to protect them when they are weak.
