Level 2-5 is the fifteenth level in Plants vs. Zombies, Plants vs. Zombies: Journey to the West, and Plants vs. Zombies: Great Wall Edition, and it is the fifth Night level. It is a Whack a Zombie level. When this level is finished for the first time, the player obtains the Hypno-shroom.
- All zombies in this level spawn from graves. Some will move fast or slowly.
- The player may not be certain whether or not to use sun for plants.
- Regular Zombies take one hit with the mallet to kill them, Conehead Zombies take two, and Buckethead Zombies take three.
- Generally, whack zombies with the mallet by clicking on them or by tapping on them if you are using a touch-screen device. Some zombies are harder to kill than others.
- Use sun to plant Grave Busters to destroy graves. Graves spawn frequently closer to the house after halfway through the level. Each grave carries a little treasure or two, so try to destroy as many as you can.
- Use a Cherry Bomb if too many zombies come on the screen at the same time (maybe in the final wave). Potato Mines are not useful in this level, although they only cost 25 sun.
- Get rid of all graves except the ones that are clustered together. Tapping around the cluster will get rid of most of the zombies.
- Get rid of the graves closest to your house, giving you more time to destroy zombies before they eat the players brain.
- Ice-shroom replaces Cherry Bomb in the non-mobile mini-game version.
- Level 2-5, Level 1-1, Level 4-5, and Level 5-10 are the only levels in Adventure Mode where there are no Flag Zombies.
- Whack-a-Zombie is a reference to Whack-a-Mole.
