''Popcorn is a bit of a nervous nelly. He takes his sweet time to get prepped for zombie fightin’. But when it’s time for his moment in the spotlight, he goes to pieces in all the excitement. It’s okay, Popcorn! You’re doing a great job! ''

Trivia
Попкорн
 * This is one of the four plants based on corn, the others being Kernel-pult, Cob Cannon, and Popcorn-pult.
 * Before it pops, when planted it takes time to swell to full size and get red, then explode when the nearest zombie eats it.
 * Mall Cop Zombies will drive over it if it has not been armed. Both of them are left untouched.
 * There is a glitch that if the player plants it on their town, it will not charge/arm but if they replant the Popcorn, it will arm.
 * This also happens when the player attacks their friends' town then flee the fight, it will arm.
 * This could be the replacement of Potato Mine for Plants vs. Zombies Adventures.
