- Sometimes, the game will spawn a Primitive Buckethead Zombie to replace one of the Primitive Conehead Zombies. It has higher health, but it's not a problem if the player has upgraded their plants.
- Club Zombie is a melee attacker, but it deals more damage than any other zombies here. It's better for the player to put a Wall-nut where the boss Club Zombie would appear.
- The two small numbers next to the zombie icon means that zombie will appear there, with the small number on the left displays the lane that the zombie will appear, and the one on the right displays the column that the zombie will appear. If there's only one small number next to the zombie icon, then it means that that zombie appears at the beginning of the lawn, and at the lane that the number displays. Example: 3-5 means that a Basic Zombie will appear in the third lane, at the fifth column. Note that this only displays the position of the zombies that have the most chance to happen.
