Winter Melon

The  is a lobbed-shot plant and the upgrade of the Melon-pult. It lobs frozen Melons that deal 4 peas of damage per melon and freeze groups of zombies at once. It costs $10,000 to buy in Crazy Dave's Shop and is only available to purchase once the player has completed Adventure Mode. Its name is based on the benincasa hispida, but it appears to be a blue palette swap of the citrillus lanatus.

Strategy
The Winter Melon is one of the most powerful plants in the game, in league with plants like the Cob Cannon, Gloom-shroom, and Gatling Pea. The Winter Melon can freeze zombies within a half-square radius and deal significant Area of Effect damage. The Winter Melon is effective against Shield Zombies. A single Winter Melon is strong enough to kill a Gargantuar by itself, partly due to the slowing effect. The Melon-pult and Snow Pea combination has a similar effect, but the Snow Pea can only affect one zombie per pea.

The Winter Melon is frequently used in Survival Mode. Because the zombie density increases dramatically over time, the splash slow effect is critical. Powerful zombies such as Football Zombies or Gargantuars appear frequently in Survival: Endless, but Winter Melons weaken them considerably. Winter Melons strategically placed in the pool rows can slow Buckethead Ducky Tube Zombies and Dolphin Rider Zombies.

Trivia

 * Strangely, if the Winter Melon is fully recharged, the player has accumulated enough Sun to purchase it, and there are no Melon-pults on the lawn, clicking on the Winter Melon seed pack causes a message to appear stating "Plant a Winter Melon first" instead of "Plant a Melon-pult first".
 * This typo was corrected in the Game of the Year version.
 * It is one of the two Upgrade Plants that cost less Sun than the plants they upgrade, the other plant being the Gold Magnet.
 * According to the Almanac, the Winter Melon can deal a very heavy amount of damage. However, it deals the same amount of damage per melon as the Melon-pult.
 * The Melon-y Lane achievement is based on the Winter Melon.
 * The Winter Melon does not have eyebrows on its seed packet.
