Powder Keg

Powder Keg is a Brain Buster in the Chinese version of Plants vs. Zombies 2: It's About Time. The player has to stop the flames from reaching the kegs to avoid explosions. If the kegs explode, the player loses the game. It is recommended to bring the Iceberg Lettuce, the Snow Pea, and the Winter Melon, as those plants can extinguish flames.
