|Oh sure, everyone knows Stunion as the battle-hardened warrior with the potent breath. But he's so much more than that. He's an accomplished pianist. He speaks five languages fluently. Heck, he's the leader of a Cub Shallots group in his spare time. Dude's got layers. Go on, peel 'em back. You'll see.|
Stunion is the fourth plant obtained in Frostbite Caves in Plants vs. Zombies 2. He is a single-use plant and when zombies get close to him, he releases a cloud of gas in a 1x2 area in front of him, similar to the one emitted from a zombie defeated by Chili Bean, stunning the affected zombies for 12 seconds. The gas cloud does not affect mechanical enemies, except for Zombie Bulls, Gargantuar Primes, Yeti Zombie, and Bug Bot Imps.
Stunion is based on the plant Allium cepa, also known as the common onion in English. It is usually used as an ingredient in cooking, thanks to its distinctively pungent taste and aroma. Its name is a portmanteau of "stun," an act of driving someone into an unconscious or semi-conscious state, and "onion," the plant he is based on.
Sun cost: 25
Stunions breathe a stunning cloud of gas on nearby zombies in the lane.

Plant Food effect
When fed Plant Food, Stunion will release a burst of gas in a 4x3 area in front of him, stunning all zombies in the said space for 18 seconds.
Stunion now releases a burst of purple gas in a 5x3 area in front of him, stunning affected zombies for twice as long.
Compared to Iceberg Lettuce, Stunion can stun all zombies in his area of effect instead of just one target. The stunning effect is not nullified by fire-based plants and also works in Frostbite Caves, where Iceberg Lettuce can only slow instead of stop enemies. However, Stunion does not work on mechs and costs more sun than Iceberg Lettuce. In most cases, though, his slightly bigger price will not matter. On the other hand, his Plant Food effect is significantly worse—while Iceberg Lettuce's plant food ability affects the entire screen, Stunion's plant food ability only affects a limited area.
In Dark Ages, Stunion can be used to prevent Jester Zombie from reflecting projectiles. However, the same is not true for Parasol Zombie and Excavator Zombie in Lost City, as they can neutralize projectiles even when stunned. If using Stunion against MC Zom-B during rap, make sure to plant him on the square that MC Zom-B is on or the one in front, otherwise MC Zom-B can kill him with his microphone which has longer effective range.
Stunion should not be used in tandem with Primal Peashooter, as the latter's knockback will remove the stun effect, rendering Stunion useless. Iceberg Lettuce should be used in this situation instead, since its freezing effect is not interfered by Primal Peashooter.
Primal Peashooter removes Stunion's effect, so it is not recommend to use them together.
Plants vs. Zombies Wiki has a gallery for Stunion.
- Stunion can stun flying zombies, unlike Iceberg Lettuce and Chili Bean.
- When a Stunion disappears, he makes the same sound as Puff-shroom when dying.
- If a Stunion stuns a zombie and that zombie dies before the effect is gone, the zombie's body will just remain there, standing still until the stun effect ends and the body collapses. The gas cannot be seen.
- If a stunned zombie is pushed back by Hurrikale and lands up on a slider tile, it will remain there until the gas disappears.
- Its tongue is green, as seen whenever he opens his mouth to stun zombies.
- Stunion and Chili Bean both use the same gas to stun zombies. They are also the only plants able to do so.
- For a brief moment after stunning, it can be shoveled for sun.
- This is similar to Ghost Pepper, which can be shoveled for sun briefly after exploding.
