Pumpkin

Pumpkin is a defensive plant in the game. Unlike the Wall-nut or Tall-nut, it does not occupy a garden space for itself, allowing other plants, besides another Pumpkin, Sea-shroom, Tangle Kelp, or a Cob Cannon to be planted, and protected, in the same spot.

The Pumpkin is obviously based on Cucurbita pepo

Powers
The Pumpkin's main power is to gain time by placing a pumpkin on another plant to protect it.

If Plant Food is given to it, the Pumpkin becames a full-sized halloween pumpkin lantern.

Trivia

 * When a Pumpkin with a plant inside is squashed, it will have a flattened animation of the plant above a flattened Pumpkin instead of a flattened version of the plant in the Pumpkin.
