- Plant Guacodiles and Parsnips close to the Zombot. This ensures that they can attack the Zombot, as well as deal with the zombies that are spawned. However, it might help to use Endurian to protect them, because their rushing attacks can actually leave the lanes open for other zombies.
- Because the Zombot attacks with missiles so frequently, it can be difficult to keep your plants alive for very long. Spread your plants out so the splash damage from the missiles cannot hurt multiple plants at once. It also uses its laser attack frequently. Although this burns up your plants, this can actually be advantageous if the lane is clogged up with dangerous zombies.
- In the later phases, be especially careful of Jurassic Rockpunchers. They are durable, and can easily smash through your defenses, and they only get more dangerous when dinosaurs assist them. Because of this, prioritize using Perfume-shroom on the dinosaurs in the lanes they are summoned in to get rid of them quickly. Spamming Guacodiles can also be effective.
- The final phase it incredibly difficult, due to the presence of Jurassic Rockpunchers and Jurassic Gargantuars, which will be assisted by a T. Rex or ankylosaurus. Use Perfume-shroom to charm the dinosaurs, or Guacodiles and Parsnips to take them out. Acting fast is crucial, as you have no lawn mowers in this battle.
- Plant Food should be used to take out masses of zombies, as well as damaging the Zombot. Parsnips Plant Food effect is particularly powerful, easily destroying zombies and dealing heavy damage to the Zombot. If all else fails, don't be afraid to use Power Ups.
- Similarly to Far Future - Day 31 and Far Future - Day 35, sometimes the beginning dialogue will be skipped. This may have to do with starting the level in the quest that is given at the start of each update.
- Like Ancient Egypt - Day 35, it gives Parsnip for the player to use.
- These are the only boss battle levels to do so.
