Lost City - Day 16 is the sixteenth level of Lost City in Plants vs. Zombies 2. Like all of the other World Key battles, the player has to survive without any lawn mowers. There are no Gold Tiles in this level due to the fact that it is a conveyor-belt level. When this level is finished for the first time, the player gets a lost city pinata.
(Dr. Zomboss appears)
Dr. Zomboss: Come here seeking adventure, have you?
Dr. Zomboss: Unfortunately for you, the Porter Gargantuars are about to ruin your day!
Dr. Zomboss: They carry imps. Imps! Prepare to become ancient history!
(Crazy Dave and Penny appear)
Crazy Dave: I wish someone would carry me around in a tiny house!
Penny: I wish for a lot of things, User Dave. That is not one of them.
(Dr. Zomboss, Crazy Dave and Penny leave)
- This conveyor-belt level starts off with several A.K.E.E.s and Red Stingers given to the player. The first enemy in the level will be a fast-moving Bug Zombie, as such the player will need to place down two offensive plants to take care of it before it can get too far.
- The level does not get tense until the first Lost Pilot Zombies drop on the lawn. By this time, the player should have gotten two Endurians. When the second wave starts, the player should start getting Lava Guavas and Cherry Bombs, but they are rare. Nearing the end of the second wave, a Porter Gargantuar will appear.
- When the last wave starts, one Porter Gargantuar will appear in every lane. Cherry Bombs are very important at this point, but using Plant Food on A.K.E.E.s will also deal a fair amount of damage to the Gargantuars. Lava Guava helps with stalling them, as Gargantuars will keep smashing its lava tile for a certain amount of time.
- The player gets around five Plant Food in this level but it can be completed without using any.
- Note: This is for the 3.6.1 version.
- The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.

- Although there is a very huge amount of zombies in this level, the plants are somewhat powerful, too, so this level is not that hard.
- A.K.E.E.s should be planted in the first or second column on the back, while Red Stingers should be planted on the third or fourth column. This is because more Excavator Zombies come than Parasol Zombies.
- Cherry Bomb should only be used on the Porter Gargantuars. If the situation is tough, it can be used on large clusters of zombies that are in your way.
- Although the Lost Pilot Zombies only have the health about a Basic Zombie, the Parachute Rain ambushes can be devastating, since the Lost Pilot Zombies drop down in big groups. Lava Guava can be a very useful plant in the latter part of the level, as the lava puddle it creates will easily destroy the Lost Pilot Zombies and Excavator Zombies, and can do significant damage to Porter Gargantuars.
- For more defense against the huge waves of zombies, at least two columns of A.K.E.E.s and two columns of Red Stingers should be planted.
- The player will get the Porter Thwarter achievement when completing this level, if he/she is connected to Google Play or Game Center.
- It is the first Gargantuar battle to have three flags.
- Unlike any other Gargantuar battles which play the Ultimate Battle theme, this one plays the Demonstration Mini-Game theme during the level.
- This Gargantuar battle as well as Ancient Egypt's, Neon Mixtape Tour's, and Modern Day's are the only ones to have more or less than three Gargantuars in the Gargantuar level.
- Ancient Egypt only has two Gargantuars on their Gargantuar level. This level has six Gargantuars, Neon Mixtape Tour has four Gargantuars in its Gargantuar level and Modern Day composes of almost entirely Gargantuars in its Gargantuar level.
- It is the first Gargantuar battle to not feature any beneficial or detrimental modifiers in the level, the second being Modern Day's.
- It is the second Gargantuar battle to not feature Wall-nut as a defensive plant, as it is replaced by Endurian. The first time was in Frostbite Caves, where it was Chard Guard.
- This is currently the first Plants vs. Zombies 2 level to have a period in the goal description. The second is Modern Day - Day 16.
