Strategies
With
Smoosh-Shroom has below-average health for his cost, and also lacks traits and abilities, but it is more useful than you think. It can hit very hard, being the second strongest mushroom in terms of raw stats, behind Template:PvZHLink. Additionally, it has tribe synergy, unlike Smashing Pumpkin since Squash plants have almost no synergy except from being conjured by a Mayflower, whereas there are countless strategies that help mushrooms.
Smoosh-Shroom perhaps benefits the most as Nightcap, as most of Nightcap's plants are quite weak, whereas Smoosh-Shroom has high strength and is not as fragile. He can use it in mushroom decks by boosting it with Buff-Shroom, using it with Punish-Shroom, or Conjuring it from Cosmic Mushroom. Other heroes don't have as much of use for it, but Green Shadow can boost it with Fertilize, Citron and Beta-Carrotina can protect it with Template:PvZHLink, and Template:PvZHLink can play tricks to deal with zombies that threaten this plant.
Do note that plants such as Shooting Starfruit and Gloom-Shroom may be better choices, depending on the situation and the hero's class, although you can use Smoosh-Shroom in tandem with those plants.
Against
Smoosh-Shroom has a lot of strength, and can take out a large chunk of health at anything it attacks. However, you can take advantage of its strength at the same time and instantly destroy it with Rocket Science or Cut Down to Size. Locust Swarm can also instantly destroy this plant. If its health has not been boosted, Cakesplosion can also get rid of it. Any zombie with 4 or more strength, or with the Deadly trait can instantly destroy it as well. However, remember that the zombie that faces Smoosh-Shroom is going to be either destroyed, or badly damaged unless you destroy it with a bonus attack or shield the zombie with Zombot Battlecruiser 5000, Zombie Coach, or Escape through Time.
