Jalapeno

The Jalapeno is a high-damage explosive that can clear an entire lane of zombies, melt Zomboni's ice and melt Dr. Zomboss's ice balls.
Its shape and name are based on the chili pepper, valued for its spicy flavor.

The Jalapeno's name is misspelled in the game; the correct spelling is Jalapeño, and because of this, the Jalapeno should be pronounced Hal-A-Peen-O as opposed to the correct Hal-A-Peen-Yo.

Jalapeno's Right eye twitches

It seems that the Jalapeno is actually sweating. This may be due to that it is hot as it is a chili, or it may just be reflections from the sun. It may also be since he is nervous about the explosion and trying not to detonate at the same time.

The Jalapeno plant in real life is not actually the hottest chili pepper. In fact, the hottest pepper, the Trinidad Scorpion Butch T Pepper is the hottest, which is 1,463,700 on the Scoville scale!

The flaming effect is, assumably, due to the spiciness of a chili when eaten.

The row of flames seems to distinguish from the left.

If you look closely, Jalapeno has green pupils.

Jalapeno can melt a frozen Gargantuar, Giga-Gargantuar or Dr. Zomboss.

The Jalapeno, Peashooter and Ice-shroom are the only plants whose names were spelled uncapitalized in one entry of the Suburban Almanac.

On the iPhone/iPod Touch version, there is an achievement called Chilli Free, where the player is not permitted to use Jalapenos in Column Like You See 'Em.

A Jalapeno can clear a lane of daisies made by killed zombies (if 'daisies' was typed).

In the Suburban Almanac, the Jalapeno is shaking fast while in the Zen Garden it shakes slow.
But however in the iPhone Version in Zen Garden, it shakes faster.

If a Jalapeno or other explosive plant is used to destroy a zombie in ZomBotany, it will turn the zombie black, but it won't fall into ashes.

The Chili Pepper T-Shirt was available in the Xbox Live Marketplace. It costs 80 Microsoft Points. It was a white T-Shirt with a picture of the Jalapeno on it.

In real life Jalapenos are normally green.

Jalapenos can also be extremely useful in Survival: Endless, to destroy Giga-Gargantuar and Gargantuar.

Jalapeno seems to have the most stress on handling the power setting off of all exploding plants.

Jalapeno's eyes are different from it's eyes in the almanac when detonating.

Jalapeno acts as an extra lawnmower.

The jalapeno will close one eye while exploding.

Melon-pult

The Melon-pult is a plant that lobs watermelons at incoming hordes of zombies. The melons smash on impact, causing damage to zombies within one square in any direction. Since its melons do 4 times the damage of a pea, and it shoots 1/2 times of a Peashooter, the Melon-pult has the same damage rate of a Repeater, but has a wider target and be used on Roof levels. Melon-pults also cost less than four Peashooters. The Melon-pult can fire over the shields of Ladder Zombie, Screen Door Zombie, and Trash Can Zombie.
Both the Melon-pult's shape and projectile are based on Citrullus lanatus, the common watermelon. This is the last plant you gain in Adventure Mode before the final stage.

Melon-pults can hit Newspaper Zombies, Screen Door Zombies, and Ladder Zombies over their shields, and Snorkel Zombies while they're underwater (like all lobbed shot plants). When you are planning to use catapults, you might want to start with a cheap lobbed shot plant, and replace it with the Melon-pult later. It is quite useful on the roof, as well, since it (like the other lobbed shot plants) can shoot over the angle of the roof, in addition to being the strongest catapult plant not obtained from Crazy Dave. You should also considerupgrading it to a Winter Melon later, if possible, as all the zombies in range will also be slowed down. Also, supporting Melon-pults with Kernel-pults is very effective, as you can temporarily paralyze zombies with its butter attack while melons smack them in the face plus additional area-of-effect damage.
Comparing two Melon-pults to a Gatling Pea and a Torchwood: A Melon-pult does only four peas of damage per second. Considering its splash damage, which is two peas per second in ideal conditions, its average damage per second per row would be, given a zombie density of one per square, 7. With a lower zombie density, this is much lower. A Gatling Pea and a Torchwood would do eight peas of damage per second, given a zombie density of 1 per square (and an extra four peas for each zombie on that square) while taking up the same space on the field. Also, the Gatling Pea and Torchwood combination (with the Repeater) takes up three slots in the seed tray. Given one zombie, three melons to die the two Melon-pults will do a meager four peas per second, and the Gatling Pea and Torchwood still does 8 peas per second. Once upgraded to winter melon, it is almost unbeatable.

Dancing Zombies

Dancing Zombies are Zombies that moonwalk across your lawn, summoning 4 Backup Dancers and may look similar to Michael Jackson, depending on the game version. It Is the 9th Zombie encountered in Adventure Mode. There is now a new Dancing Zombie with new Backup Dancers.

The Dancing Zombie dances onto the lawn and summons four Backup Dancers, which appears somewhat like a straight cross. These five zombies will dance at the same rate, and will stop moving if one of them has to stop or is slowed down through freezing. If one or more Backup Dancers die, and the Dancing Zombie is still alive, it summons Backup Dancers until it dies.
Note: The newer version of Dancing Zombie is slightly stronger. The older Dancing Zombie always summons Backup Dancers on the second column from the right, while the newer version of the Dancing Zombie summons them on the first column. The newer Dancing Zombie also eats faster than the older one.

Absorbs 17 normal damage shots. Appearance changes upon absorption of 9 normal damage shots.

Torchwood

The Torchwood lights regular peas on fire when they pass through its flame, adding extra damage and an additional attack to enemies that are near. When planted during the Fog levels, it clears the fog around it for approximately one-and-a-quarter squares. The only other plant that can eliminate fog until eaten is the Plantern.
Although there is a flowering plant family known as Torchwood (Burseraceae), which includes frankincense and myrrh, the name may also be a reference to the eponymous organization in the Doctor Who spin-off series.

Place Torchwoods in any lane in front of any plant that shoots peas to turn the peas into flaming projectiles that do double the normal damage. It also adds splash damage which deals a normal pea's damage to all nearby zombies. However, if a frozen pea passes through it, it will melt, becoming a normal pea that does normal damage. Any zombie with a shield will prevent the splash effect. A flaming pea also defrosts zombies, so using them in combination with Ice-shrooms, Winter melons and Snow peas is not reccommended.
