The barrel is a type of armor that has different purposes in different games, including Plants vs. Zombies Adventures, Plants vs. Zombies 2, Plants vs. Zombies: Garden Warfare, Plants vs. Zombies: Garden Warfare 2 and Plants vs. Zombies Heroes.
In Plants vs. Zombies Adventures, the barrel was worn by Barrel Zombie; it increased this zombie's health. If the barrel was destroyed, they would have moved faster.
In Plants vs. Zombies 2, the barrel is used by Barrel Roller Zombie to crush plants. It contains two Imp Pirate Zombies, which will be released after the barrel is broken. Spikeweed, Spikerock, Bamboo-shoot, and a hiding Cactus can destroy it instantly. Like other shields, it blocks Snow Pea's slowing effect and lobbed shots will hit the zombie, instead of the barrel. In expansion levels of Pirate Seas, a broken barrel is also worn by Barrelhead Zombie as protection.
In Plants vs. Zombies Adventures, the barrel absorbs 12 shots before breaking and does not degrade. It can be instantly destroyed by Flaming Pea, leaving nothing but a pile of planks left.
In Plants vs. Zombies 2, the barrel pushed by Barrel Roller Zombie absorbs 1100 damage per shots and degrades upon absorbing 380, 740, and 1100 when the barrel is destroyed. It can be instantly destroyed by Spikeweed, Spikerock, or hiding Cactus.
The barrel worn by Barrelhead Zombie absorbs 2200 damage per shots and degrades upon absorbing 740, 1480 and 2200 when the barrel falls off.
