Mushroom Grotto is a galactic uncommon plant environment card in Plants vs. Zombies Heroes, and a member of the Kabloom class. It costs 3 to play, and its ability makes a Puff-Shroom on another random lane when a plant is played in it, unless all other non-aquatic lanes are occupied by two plants.
Its name is a combination of "mushroom," referring to its appearance and ability, and "grotto," referring to its description, which is a reference to the fact that mushrooms grow in dark places.

While Mushroom Grotto makes Puff-Shrooms, which are very weak plants, the true strength of this environment is the sheer number of Puff-Shrooms it can make.
Since making plants counts as playing them, Astro-Shroom, Muscle Sprout, and Go-Nuts are able to activate their ability multiple times, making them (and the Puff-Shrooms too in the case of Go-Nuts) very big threats.
Other examples of plants that synergize well are those whose ability becomes more effective when there are more plants on the field. Such examples are Buff-Shroom and Pineclone, who are able to make the Puff-Shrooms this environment more powerful. You can take it one step further and play Molekale, resulting in a ton of 5 plants on the field. If you think your opponent will try to wipe the Puff-Shrooms or this environment off, Punish-Shroom will severely penalize your opponent. Since Puff-Shroom has Team-Up, you should have no problem filling the field.
To make more Puff-Shrooms at once, play plants that can make Team-Up plants like Pair of Pears or Shroom for Two because they can make two Puff-Shrooms in random lanes compared to only one. That way, you can fill the field faster. If multiple Mushroom Gorottos are present, it is possible that a Puff-Shroom will spawn on a Gorotto, therefore activating its ability and causing a chain reaction. To make this happen faster, occupy the height lanes.
However, you have to be careful against Supernova Gargantuar as it can destroy all of your Puff-Shrooms made from the environment very easily.
Since Puff-Shrooms are weak with only 1/1, try to play area of effect instant-kill or damaging cards, like The Chickening, Weed Spray, Barrel of Deadbeards, or Fireworks Zombie. However, playing any of those when Punish-shroom is on the field is not a good idea. Supernova Gargantuar is much more expensive, but can easily take over all of the Puff-Shrooms made from the environment. You can also replace this environment with one of yours to prevent the plant hero from making swarms easily. Extinction Event is also a good card to use as it is cheap and you can use it after they swarm the field with Puff-Shrooms.
