- The Explorer Zombies and Ra Zombies could deal much damage to the player's defensive plants.
- The Conehead Mummy, Buckethead Mummy and Tomb Raiser Zombie had pretty high health. Use the plants' Plant Food skill to kill them if needed.
- The two small numbers next to the zombie icon mean that zombie appeared there, while the small number on the left displayed the lane where the zombie would appear, and the one on the right displayed the column that the zombie appeared in. If there's only one small number next to the zombie icon, then it means that that zombie appeared at the beginning of the lawn, and at the lane that the number displays. Example: 3-5 means that a Basic Zombie appeared in the third lane, at the fifth column. Note that this only displays the position of the zombies that have the highest chance of spawning.
