Pumpkin

The Pumpkin is the third defensive structure in the game. Unlike the Wall-nut or Tall-nut, it does not take occupy a garden space for itself, allowing other plants (besides another Pumpkin or a Cob Cannon) to be planted, and protected, in the same spot. Other plants can also be placed in an empty Pumpkin. Pumpkins have the same health as the Wall-nut. Like the Wall-nut and the Tall-nut, you can plant a new Pumpkin over a damaged one without replanting it if you have purchased Wall-nut First Aid from Crazy Dave's shop.

Strategy
Pumpkins are excellent on later levels, where the player needs to take out as much space as possible. Catapult Zombies and Bungee Zombies always target the plant inside the Pumpkin first, so they are useless as protection against them. They can be used to buy time so that your plants have more time to take out Digger Zombies. The best plant to put inside a Pumpkin (for defensive purposes) is the Tall-nut, so Pole Vaulting Zombies or Dolphin Rider Zombies cannot jump over them, and the zombies will still have to eat the Pumpkin, and when they break through the wall they have to eat the Tall-nut, so it saves time focusing on attack. Note, however, that it is not as efficient, sun-wise, as a Tall-nut alone; a Tall-nut and Pumpkin combo costs as much as two Tall-nuts, yet has less health than two. They are also useful for plants that the Imitater duplicates, because it protects them as they transform.

Don't put plants that are supposed to be eaten into a Pumpkin, such as Garlic or Hypno-shrooms. The zombies will have to eat the outside Pumpkin before eating the plant, so doing so will result in a waste of Sun. Pumpkins are usually good along with Potato Mines, as they give the Potato Mine time to arm, and once the zombies break through the Pumpkin, they will have come together onto one spot and will all be hit by the Potato Mine. The only problem with this is that, because of their larger horizontal hit-box, Football Zombies will trigger the Potato Mine while it is inside the Pumpkin, only killing some of the zombies as they will not all count as in range. As a result, it may make more sense to use a Wall-nut to protect the Potato Mine instead as it is cheaper and will allow time for all of the zombies to get in range.
