Pumpkin

Pumpkin is a material added in the 1.2.1 Hallowen update. It is harvested from the Pumpkin plant (similarly to harvesting Cactus) which is available year-round from Pumpkin Seeds bought from Dryad and will grow naturally in random places during the Halloween season, it can only be planted on grass. Harvesting pumpkins will rarely yield a Magical Pumpkin Seed, which is used to summon the Squashling pet.
