Turbo Button

The Turbo Button is a tool added to Plants vs. Zombies 2 in the 1.7 update. It allows the player to fast forward the level, making the zombies, plants, seed recharge, and almost everything go faster. The player can toggle the on and off settings on the Turbo Button as much as they want, as it's available at anytime on any level.

In the Chinese version, the Turbo Button is a gem premium feature available for 18 gems. However, the Turbo Button can be unlocked for free by entering a special code into the game. This code will additionally unlock gems, Cherry Bomb, and coins.

Usage
The Turbo Button is best used at the very beginning and the end of a level, in order to start off right and make sun fast in order to get the lawn ready as soon as possible. It has been also reckoned to serve the recording of playthroughs/walkthroughs, allowing the videos to be shorter.

Trivia

 * When the Turbo Button is on, if a zombie gets to the second tile of the lawn, the fast forward effect will automatically shut down, returning the level to normal speed. This is because it can tell the player a zombie is about to enter the Player's House.
 * However, the player can still re-activate it afterwards.
 * In Endless Zones, there is a glitch that sometimes the Turbo Button will be reversed, so if it is on, the game will be in its normal speed, and when it is off, the game will speed up.
 * While the Turbo Button is on, all sounds effects have a higher pitch.
 * If you activate the Turbo Button after you reward pops up at the end of a level, it will amusingly speed up the downtime & you will collect the prize faster along with any coins from leftover lawnmowers . (~)
 * Also amusing if done at the end of Vasebreaker Endless, it will load the finish screen faster, plus set all the new vases down quicker along with the "ready, set go!" start up. (~)
