The ladder is the only object that zombies can climb over. It can be destroyed with an explosive plant or it can be pulled away with a Magnet-shroom, even after it has been placed. It is imperative that it is destroyed quickly so zombies do not take too much advantage of it. Even when the Cattail shoots a spike to Ladder Zombie's back, the damage is dealt to the ladder. If a Tall-nut or Wall-nut in a Pumpkin has a ladder placed on it, removing the plant will remove the ladder. Sometimes, it can become an advantage when using Gloom-shrooms.
- The price of the ladder according to the Ladder Zombie's Almanac Entry is a bit underpriced compared to a real ladder.
- When a zombie is slowed, it can still climb up the ladder at normal speed.
- When zombies climb the ladder, there is no climbing animation.
- The ladder can only be damaged by instant kills after it is placed.
- The ladder will always appear undamaged when it is placed.
- If you manage to hack in a miniature Ladder Zombie, the ladder will be full-sized when placed.
