As mentioned above, this achievement is obtained only by beating Day 16. The Gargantuar battle of Lost City is one of the easier ones as the player is given strong plants such as Cherry Bomb and Lava Guava, as well as a lot of Plant Food in case of an emergency. Therefore, the player should follow the tips laid out on the aforementioned level page. In any case, only the fifteen levels that take to get to Day 16 are what make this achievement harder to earn.
- It cannot be achieved by completing Lost City - Day 12, despite this level having a Porter Gargantuar in it.
- In the achievement's description, it incorrectly calls the Porter Gargantuar as the 'Lost City Gargantuar'.
- It is one of four rhyming achievements in Plants vs. Zombies 2. The others are Pod Squad, Fungus Humongous and Tile Denial.
