Extras

Extras is a game mode in Plants vs. Zombies: The Last Reminiscence. It is unlocked after completing all five worlds in Storyline mode and is accessible through the menu screen. This mode contains packs of levels, each level has various twists and the player has to complete certain objectives to win the level. Certain levels will also let the player try plants that cannot be unlocked in Storyline mode.

Turbulence
Turbulence consists of five conveyor-belt Cloudy Skylands levels. However, a while after the level starts, a message "Turbulence!" will appear on screen, and Skyquakes will occur continuously (every time plants and zombies are standing still on land), causing plants and zombies to switch lanes non-stop. Due to this, zombies cannot enter the house. Note that air plants will not be affected by Skyquakes. To win the levels, the player must defeat all zombies as well as complete objectives of "Never have less than X plants", "Never have more than X zombies".
