Ladder Zombie carries a ladder that functions as a shield, similar to Screen Door Zombie's screen door, and is the 21st zombie encountered in Adventure Mode. It moves faster than other zombies while it has its ladder. In addition to functioning as a shield, the Ladder Zombie can also use its ladder to get over the first defensive plant (Wall-nut, Tall-nut, Pumpkin, or an imitated version of said plants) it encounters. It leaves the ladder behind, allowing other zombies to climb over said defensive plant, and continues at normal speed to eat the remaining plants. Ladder Zombie can eat other non-defensive plants, even if it encounters them before placing the ladder. For example, if the player has a Sunflower in front of a Tall-nut, it would eat the Sunflower, place the ladder on top of the Tall-nut, climb over the Tall-nut, and keep going.

He picked the ladder up for $8.99.
Ladder Zombie loses its ladder upon placing it to get over a defensive plant, therefore losing the remainder of the ladder's hit points. Any damage that Ladder Zombie itself sustained (from lobbed projectiles, fumes, Spikeweeds, Spikerocks, or projectiles from behind) remains in place.

Ladder Zombies can be annoying because they can easily get over your defenses, also letting other zombies do so too. However, there are various ways to deal with this zombie. The ladder can be taken away by a Magnet-shroom, even if the ladder was already placed. Instant kills, (Cherry Bombs, Jalapenos, Doom-shrooms, and Cob Cannon cobs) will also destroy the ladders after they are placed. These zombies are also weak to Fume-shrooms, Gloom-shrooms, Spikeweed, Spikerocks, and lobbed-shot plants (the lattermost of which should compose the majority of your offense in the roof levels in which the Ladder Zombie appears), as they deal damage directly to the zombie and do not have to destroy the ladder first. The ladder can also prove to be a weakness to the Ladder Zombie, as Split Peas, Starfruits, and Gloom-shrooms can shoot backwards to damage the zombie directly, making it a good idea to plant them in Pumpkins. This would effectively make the plant invulnerable until an explosive plant or Magnet-shroom is utilized or a Jack-in-the-Box Zombie blows up near it, so you shouldn't use both of these techniques at once (or near each other). Of course, this would not be helpful against Gargantuars or Zombonis. Ladders are best for a Chomper inside a Pumpkin, since the Chomper will be left untouched (passed over) while still eating zombies. This works especially well if the Chompers are planted on the right side (forefront) of the lawn/roof, but obviously not very well if planted too close to house.
It should also be noted that if he places the ladder on a defensive plant (such as Wall-nut, Tall-nut, etc), the plant can be dug up to remove the ladder. Although, this is not recommended as defensive plants have a very slow recharge and can cost up to 125 sun. Only do this as a last resort, such as if a Jack-in-the-Box Zombie can climb on it and explode plants towards the inner part of your defenses.
When used properly, Ladder Zombies can quickly overrun rows with large amounts of Peashooters and other similar plants. You should consider using Ladder Zombies instead of Bungee Zombies to render useless Wall-nuts or Tall-nuts, rather than send plenty of zombies to get over the defensive plants. However, don't use them near Magnet-shrooms, as they will remove or steal the ladder. If there are no defensive plants in a row, they can be a usable substitute for the Screen Door Zombie, with a shield to protect against the freezing effects of Snow Peas, and faster movement to compensate for the lower health. Above everything, avoid placing Ladder Zombies in rows with Kernel-pults, Spikeweeds, or Fume-shrooms, as they will die quickly from the direct damage. Usually when Snow Peas are around, they work better than Football Zombies, being fairly cost-effective (150 sun for Ladder vs. 175 sun for Football).
On very well defended lanes with Snow Peas, where a single Ladder Zombie would not complete the lane and get the brain alone, they can work well by teaming them with a Football Zombie. They work well when they are both near, with the Ladder Zombie first, which's role is protecting its Football Zombie partner from frozen peas. Usually, when both of them will encounter a plant and eat it at the same time, Football Zombie's hitbox will cover the Ladder Zombie's one, freezing the Football Zombie, but it does not matter because after the plant disappeared, Ladder Zombie will walk faster than his partner but, protected from frozen peas, it will finally get his normal speed back and get to the Ladder Zombie again when this one will be stopped eating a plant. This team often works better than two Football Zombies together. It also costs 25 sun less.
To be extremely economical, a Ladder Zombie can also pair up with another low health Zombie, for example Pole Vaulting Zombie. When the Ladder at hand degrades for the second time, send off the Pole Vaulter to quickly catch up the battlefront, who either sacrificially absorbs damage and saves the Ladder Zombie, or ends up surviving (typically benefited from vaulting over one plant) and finishes the row. This strategy is meant to reduce the cost (down to 225 sun or so) for the row of interest.
- Ladder Zombie is one of the two zombies that has a shield used for something more than just protection, the other being Excavator Zombie.
- The ladder is a shield against head-on projectiles. It provides no protection against fume attacks, arcing catapult projectiles, attacks from below (such as those from Spikeweed and Spikerock), attacks from the back (e.g. behind a laddered Split Pea), and instant-kills.
- Ladder Zombie is the only zombie that is told to have money, since the Almanac entry states that it bought the ladder for $8.99.

- Ladder Zombie only puts his ladder down when he reaches a Wall-nut, Tall-nut, or Pumpkin, but not when reaching a Garlic.
- Ladder Zombie will not eat defensive wall plants when its ladder is intact.
- A ladder will disable but not destroy one defensive wall plant. Most zombies approaching from the right side of the screen will climb over it. A Digger Zombie approaching from the left will still attack a defensive plant with a ladder attached.
- Unlike Newspaper Zombie and Screen Door Zombie, the ladder protects hypnotized Ladder Zombies.
- Even if the Ladder Zombie loses its ladder, it won't still use its hands to eat plants like of most of zombies do.
- The same thing happens with Newspaper Zombie.
- Ladder Zombie actually eats further away from plants than other zombies. This also occurs with Newspaper Zombies.
- In the DS version, even if the ladder is damaged, while the Ladder Zombie is eating, it appears to be undamaged.
- A placed Ladder can be destroyed by an explosive (Cherry Bombs, Jalapenos, Doom-shrooms, Cob Cannons, and Potato Mines) or by digging up the plant that it is placed on. Placing a Magnet-shroom within range will remove ladders, even if they have already been deployed.
- If the player kills a Ladder Zombie in the progress of placing a ladder, its head will fall off, stop, and fall. The ladder will also disappear.
- Even if the ladder has taken damage, the ladder will look undamaged when placed on a Wall-nut, Tall-nut, or Pumpkin.
- Ladder Zombie, Imp (while flying), Balloon Zombie (while using its balloon), Digger Zombie (while digging), Gargantuar, Zomboni, and Catapult Zombie are the only zombies that can get past a Tall-nut by itself without eating the plant.
- The Gargantuar, Zomboni and Catapult Zombie crush the Tall-nut instead.
- Even if Ladder Zombie's ladder is undamaged, it will change appearance to look damaged if the zombie dies while carrying it. The same thing happens with the Screen Door Zombie and Newspaper Zombie.
- Ladder Zombie has a pencil stuck in the side of its head, a tool belt with a hammer, and a plaid workman's shirt.
- Ladder Zombie has the same speed as the Pogo Zombie while holding his ladder. If he loses his ladder (deployed, magnet, broken), he slows down to the speed of a normal zombie.
- There is a glitch that when a Magnet-shroom behind a Tall-nut or in a Pumpkin steals the ladder. the zombies can still climb over the Pumpkin or Tall-nut, as if the ladder was deployed.
- When an Ice-shroom is activated or a plant is upgraded inside a Pumpkin with a ladder, it is destroyed.
- Another cause of disappearing ladders against Pumpkins is removing the plant inside the Pumpkin.
- Ladders are sometimes used in strategies in Survival: Endless to make plants invulnerable to eating zombies.
- Ladder Zombie, the ZomBotany Zombies, Dancing Zombie, and Jack-in-the-Box Zombie are the only zombies that can use their abilities when hypnotized.
