If the player hypnotizes a Peashooter Zombie or a Gatling Pea Zombie, it will still shoot at his or her plants through the back of its head. However, it will still eat other zombies. Hypnotizing a Jalapeno Zombie causes it to explode once it leaves the screen and destroys the player's plants, despite being a friendly comrade.
Even though freezing Peashooter Zombies with Ice-shrooms or butter prevents them from shooting peas, slowing them down with Snow Peas, Winter Melons, or the residue left behind by Ice-shrooms do not hamper that ability.
Apparently, the zombies' instant kills are stronger than that of the plants' instant kills, since the Squash Zombie can kill the Tall-nut in one hit while the plant Squash requires two hits to kill the Tall-nut Zombie.
In the iPad version, the Gatling Pea Zombie's head looks as if were kind of floating off the body, with a stem supporting the head.
This is the only Pool level that does not have ambush zombies.
In the icon for the iPad version, it shows a Jalapeno Zombie and a Gatling Pea Zombie at night.
According to LawnStrings, this mini-game's original name was going to be War and Peas 2, with "War and Peas" mostly likely being a pun on "War and Peace." A box with the words "War and Peas" is visible in Crazy Dave's Twiddydinkies.
In the iPhone and Android icon for ZomBotany 2, It has Gatling Pea Zombie instead of Peashooter Zombie on it.
Gatling Pea Zombie also has a visible stem where the neck is and has no eyebrows.
Upon restarting many times, there is a chance that Jalapeno Zombie will not appear.
