Sea-shroom

The Sea-shroom is the aquatic version of the Puff-shroom, but with slow recharge and can be planted anywhere in the Pool.

Suburban Almanac Entry
 Sea-shroom

Sea-shrooms are aquatic plants that shoot short ranged spores.

Damage: normal

Range: short

Must be planted in water

Sleeps during the day

Sea-shroom has never seen the sea. It's in his name, he's heard loads about it, but he's just never found the time. One day, though, it'll go down.

Cost: 0

Recharge: slow

Strategy
Plant Sea-shrooms on the third and fourth columns from the right side of the lawn, and try to put a row or two of Fume-shrooms behind them.

In the second and third columns from the left it is a good idea to plant Scaredy-shrooms as backup. You may want to plant defensive plants in front of them, although this isn't necessary. The Sea-shroom has a slow recharge rate as it covers two rows less than Puff-shroom. But this means that you can't easily replace Sea-shrooms that are eaten, making them a lot less disposable (although purchasing the Imitater helps a lot). However, it's not a very good idea to use it for the Dolphin Rider Zombie to make him lose his dolphin as its recharge cost takes a lot of time (unless you have the Imitater Sea-shroom). Of course, a Puff-shroom on a Lily Pad is effectively the same, although it costs 25 more Sun. In Survival: Endless, you can plant these in the first few flags, you can plant a few of these (and the Puff-shrooms as well) to slow the zombies down (no Coffee Beans). Also note that, unlike the Puff-shroom, Sea-shrooms are not immune to the projectile attacks from the Peashooter Zombie and Gatling Pea Zombie.

If you are in a hurry to get lots of cheap defense on Fog levels, you are much better off using Puff-shrooms on Lily Pads. It only costs 25 Sun per Puff-shroom and is immensely quicker recharging than using Sea-shrooms. Sometimes it is very inconvenient that the Sea-shroom has a slow recharge. Using Imitaters helps you set up one for each pool lane in almost no time. After the mandatory 30 seconds, you can have four Sea-shrooms at no cost.
