Mallet

Mallets are small, wooden hammers used in Plants vs. Zombies in Whack a Zombie, Vasebreaker, and on iOS and Android Last Stand and Survival.

Last Stand
One mallet can kill a zombie instantly. For the Gargantuar, it will take four hits, and eight for a Giga-gargantuar. They can be obtained from Crazy Dave's Twiddydinkies. Three mallets cost $3,000, six mallets cost $5,000, and nine mallets cost $7,000. When the player first plays Last Stand, they will have five free mallets.

Whack a Zombie
In Whack a Zombie and Level 2-5, the mallet is used to kill zombies. However, unlike the mallets in Last Stand, there's only one mallet in Whack a Zombie that can be reused an infinite amount of times. Also, it takes more hits to kill some zombies. A Conehead Zombie lasts two hits, while a Buckethead Zombie lasts three hits. Every time a zombie is killed, a small "POW" appears on the screen.

Vasebreaker
The mallet also appears in Vasebreaker, but the player only uses it to break the vases.
