Punish-shroom

Punish-shroom is a mushroom plant in Plants vs. Zombies: The Final Showdown, based on the Punish-Shroom from Plants vs. Zombies Heroes.

The Punish-shroom will deal 100 DPS to zombies that destroy any mushroom plant onscreen, including Puff-shrooms and other free mushroom plants.

If a group of zombies defeat the same mushroom (in other words, a group were all chewing on the mushroom), then all of them will receive the damage from Punish-shroom, making it effective against bunched up groups.

It is unlocked by purchasing it from Burt's Bits & Bobs for $15,000, after fully upgrading the Mold Colony.

Strategies
Punish-shroom is a powerful, albeit expensive, plant. Dealing five peas of damage to zombies for simply destroying a mushroom, especially when Puff-shrooms are free to plant, is very powerful, especially if you use Imitater to plant Puff-shrooms faster and flood the screen with plenty of them.

If you plant multiple Punish-shrooms, their attacks will stack, making Punish-shrooms and Puff-shrooms a perfectly viable defence without support in many night-time levels, although they may need support. Bunching up zombies with slowing or stunning plants, or defensive plants is a good idea, as it will allow you to maximise their power by attacking groups at once.

Punish-shroom also shines against Gargantuars, as Puff-shrooms are already an effective method of stalling them. However, attempting to beat multiple Gargantuars in different rows with Punish-shrooms and Puff-shrooms might be difficult.

The biggest weakness of Punish-shroom is its recharge timer. This makes planting enough of them for a viable defence take quite a long time, and while you could use Imitater to speed this up, this means you can't spam Puff-shrooms as fast, severely weakening the strategy.
