Sun-shroom

Sun-shroom is a mushroom which works as an alternative to the Sunflower for use at night when sun is more difficult to come by. When first planted, it will produce smaller sun that is worth less than normal. However, it will grow within time and produce regular sun.

Plants vs. Zombies
Sun-shroom is obtained after beating level 2-1. Just like the Sunflower, it produces sun every 24 seconds. When first planted, it will produce smaller sun that are only worth 15 sun. Then, it will grow to full size and produce regular sun.

Plants vs. Zombies 2: It's About Time
Sun-shroom returns as the first plant that is obtained in Dark Ages. Unlike the first game, it has three stages. Sun-shroom will produce 25 sun in their first stage. Then 8 seconds later, it will grow larger and produce 50 sun. After 28 seconds, Sun-shroom will grow to full size and produce 75 sun.

Sun-shroom hates sun. He hates it so much that when it builds up in his system, he spits it out as fast as he can. He just won't abide it. To him, sun is crass.

Oh sure, Sun-shroom is known for his ever-present grin and sunny disposition. But truth be told, even he has his dark days. It ain't easy keeping things light when you live in the shadows.

Usage
It is used as a Sunflower in the Night and Fog areas, but in exchange for its cheaper cost, Sun-shroom only produces 15 sun (instead of 25) for the first two minutes, after which it to full size and begins to produce 25 sun at a time.

In Plants vs. Zombies 2: It's About Time, Sun-shroom grows much quicker than in the first game. Also, once it has reached its final phase of growth, it will give the player 75 sun each time.

Plants vs. Zombies
Sun-shrooms are vital during the night. Even though they only produce 15 sun at the two first minutes, they quickly grow to full size. Additionally, because of the lower cost, two can be planted immediately giving an income of 30 sun, which gives you sun at a more efficient rate than a Sunflower. Sun-shroom should be used on every regular Night and Fog level due to the lack of sun and its efficiency. The lack of an upgrade for it does hinder it in Survival Mode, however.

Plants vs. Zombies 2: It's About Time
Sun-shroom will not sleep during the day and produce 25 more sun than a Sunflower, deeming Sunflowers useless. However, when compared with the Twin Sunflower, the Sun-shroom, although being cheaper, produces 50 less suns than Twin Sunflower. Sun-shrooms are preferable in days having objectives "Spend no more than value sun."

A boosted Sun-shroom is very helpful in Endless Zones, as they produce 225 sun when planted. The player will gain 200 extra sun by planting a single Sun-shroom. Sun-shrooms combined with Twin Sunflowers can be very helpful to plant expensive plants, such as Winter Melon and Tile Turnip.

They are also great being planted in columns, and you will not have too waste much sun. You can plant them in two or even three columns. This strategy is great in every world.

General

 * Sun-shroom's design looks like, and may be a reference to, the Super Mushroom or Toad from the Super Mario series. It could be a reference to the fact that mushrooms in the Mario series make your character grow, while the Sun-shroom grows itself.

Specific to Plants vs. Zombies

 * Puff-shroom and Sun-shroom are the only mushrooms that can avoid Peashooter Zombies' and Gatling Pea Zombie's peas even if the Sun-shroom has grown. They share this trait with the Lily Pad, Potato Mine, Spikeweed and Spikerock but, if the player plants the Puff-shroom or the Sun-shroom on a Flower Pot, it will get hit.
 * Sun-shroom is the only mushroom that smiles.
 * Sun-shroom, the Sea-shroom and the Puff-shroom are the only plants which, when planted, may be off-center of a square on the lawn or water. They may get planted slightly to the left or right.
 * Sun-shroom is the only plant with no shadow in the Almanac.
 * According to the Almanac, it says that Sun-shroom hates sun so much that it gets thrown out of the system when it is produced.
 * Sun-shroom, Potato Mine, Imitater, and Scaredy-shroom are the only plants can change form without being eaten.
 * Sun-shroom produces five small sun before growing in full size (ten for online version).
 * However, on the online version, Sun-shroom produces sun significantly faster than Sunflower (about twice as fast), so it still takes the same amount of time to mature as Sun-shroom for any other version.
 * Sun-shroom also makes a cameo appearance in the introduction of Peggle Nights, a game also made by PopCap Games.
 * Sun-shroom, the Twin Sunflower, the Puff-shroom, the Sunflower, the Sea-shroom and Imitater versions of them are the only plants not allowed to be used in Last Stand and Last Stand Puzzle Mode.
 * Sun-shroom seems to be the "main" mushroom because it is shown in the achievements Good Morning and No Fungus Among Us, similar to how the Sunflower is the main symbol of the plants.
 * This, along with the Sunflower, Twin Sunflower, Flower Pot, Lily Pad, Plantern, Marigold, Coffee Bean, and the Gold Magnet are the only plants that have neither offensive nor defensive capabilities.

 * It is the second of the two shrooms that blushes, the first being the Fume-shroom.
 * Sun-shroom bounces twice before growing.
 * Its first stage is the only animation that is not rocking back and forth. Instead, it bounces up and down.
