PVZ 2: Pea-Nut

Pea-nut has both defensive and offensive capabilities. This additional flexibility allow it to be planted either in the front or the rear.

Pea-nut is an offensive and defensive gemium plant that appears in Plants vs. Zombies 2 while also being tied to Dark Ages Part 2. He was released on June 22, 2014, and was available for purchase for $2.99 (although there was a discount where he cost $0.99 starting July 20th). He can now be purchased for 100 gems permanently. He is also the second Premium plant to Dark Ages introduced in part 2.

Pea-nut is a combination of Peashooter and Wall-nut: he can shoot peas at zombies that deal as much damage as a pea while absorbing damage like a defensive plant. However, if Pea-nut suffers from too much damage and has reached his second degrade, his fire rate is halved (except in the Chinese version).

Pea-nut is based on the real life Arachis hypogaea, a grain legume commonly known as peanut in English. His name is also related to his ability: "Pea" refers to Pea-nut's ability to shoot peas like Peashooter, while "nut" relates to Pea-nut's similarity to Wall-nut, as both are defensive plants.
His description is a reference to the fact that some people are allergic to peanuts.

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.
