Starfruit

The Starfruit is a plant that attacks with stars in five directions. The Starfruit's attack consists of 5 star-shaped projectiles going in five different directions: one to the left, one going straight up, one going straight down, one going to the upper right (gradient of 1/2), and the last going lower right (gradient of -1/2). Each star does normal damage. It fires these projectiles any time a zombie crosses and of its lanes of fire, so plant multiple Starfruit a bit back from your intended target and overlap their lanes of fire. If a zombie is exactly in front of the plant and/or eating it, it will be damaged by two to five sides of the Starfruit.

The actual starfruit is the Carambola[1], fruit of the Averrhoa carambola, a tree that grows in Indonesia, Sri Lanka and India. The fruit is sweet and extremely juicy, and in cross-section, appears to be a five-pointed star, hence the name.

Starfruit has almost always been misunderstood. Starfruit tend to do their best work when zombies are slowed down in other lanes. Actually with their 5-way projectiles, 125 sun cost is very cheap compared to Threepeater (325 sun cost for 3-way projectiles). The real power of Starfuit is when they're arranged vertically(fill a row) or horizontally(fill a lane or two). It's better to use them horizontally while Garlic planted in front of them, because their straight-up and straight-down projectiles is not useless. But if there are Gargantuars or Zombonis, you should use the vertical formation, because the Garlic is useless as they will smash or crush them. But, you are probably better off using Split Peas or Magnet-shrooms if you are only dealing with Digger Zombies. If you don't need range, two or three Gloom-shrooms combined with Garlic should do instead.

Seeing Stars Mini-game
You don't have any choice here, you have to plant Starfruit wherever there is a Starfruit outline - no other plants can be planted there (except the Pumpkin). In order to win the game, you have to plant one Starfruit in each outline. Just build up a regular defense with a row of Sunflowers in back, with a row or two of Peashooters and Snow Peas, to protect the house as you set up the Starfruit. For the third lane, plant a garlic on the left-most row.
