Mush-shroom

The Goop-shroom is an instant-use mushroom plant in Plants vs. Zombies: The Final Showdown which covers all zombies onscreen in goop.

It uses the same goop as the Goop-shroom, causing 20 DPS every second to every zombie onscreen, permanently. In addtion, this goop reduces the attack speed of affected zombies by half, making it easier to stall them with defensive plants.

It is unlocked after beating Night 5 of The Great Graveyard.

Strategies
Due to its free cost and ability to damage and debuff everything onscreen, the Mush-shroom is a useful plant to have in any night-time level. It easily thins out hordes of weaker zombies, works well against huge waves, and helps out a little against strong zombies that show up early on, such as early Bucketheads. As the recharge timer is the only restriction on how often you can use it, it is worth noting that this plant is a great choice for Imitater, allowing you to goop zombies very regularly.
