Pumpkin

Pumpkins are a recurring motif in The Legend of Zelda series. They occur sometimes as a visual element, sometimes as an item, sometimes as a breakable container, and sometimes as a combination of these.

A Link to the Past
In A Link to the Past, the trees in the Dark World strongly resemble pumpkins. From an aesthetic standpoint, this fits with the monstrous and spooky theme of the Dark World, as pumpkins are associated with Halloween and therefore with evil spirits and monsters. While the trees in the Light World drop apples or occasionally bees when dashed into, Dark World trees talk to Link or drop bombs.

Oracle of Seasons
In Oracle of Seasons, the trees in Subrosia are very similar to those found in the Dark World in A Link to the Past for unknown reasons.

Oracle of Ages
The first boss in Oracle of Ages is Pumpkin Head, who, as its name suggests, is a spirit with a pumpkin (specifically a Jack-o'-lantern) for a head. This continues the theme of pumpkins as a symbol of evil spirits seen in A Link to the Past.

Four Swords Adventures
Four Swords Adventures features the Dark World at various points during the adventure, and thus the pumpkin-like Dark World trees make their return.

Twilight Princess
Pumpkins feature prominently in Twilight Princess as one of the main exports of Ordon Village. In Ordon Village, Link can find pumpkins in the fields. These can be smashed to get pumpkin seeds, which are the primary ammunition for the Slingshot. The scarecrows near Link's House also appear to have pumpkins for heads. An Ordon Pumpkin is also found in a chest in Snowpeak Ruins, although Yeta misremembered the chest as containing the Bedroom Key. When added to the Simple Soup, the Ordon Pumpkin converts it to Good Soup, which restores four hearts as opposed to two.

Skyward Sword
Pumpkins feature even more prominently in Skyward Sword, thanks to the presence of Pumpkin Landing. This island is the home of a sizable (by Zelda game standards) pumpkin patch and the Lumpy Pumpkin, a pub specializing in Pumpkin Soup. Even the decor of the establishment is pumpkin-themed, as are the names of the father and daughter who staff it. Pumpkins can also be found on the main island of Skyloft in smaller patches. As in Twilight Princess, pumpkins can be smashed, although they yield a variety of items, as jars do.
