Pumpkin seeds are now available!
At the Lykosorian provisioner, a seed for 12 halloween supplies tokens.
They are an easy-level crop, and a fast growing one too. Once you plant it, it will start producing pumpkins after 10 minutes, and reaches full capacity and lifetime production about 45 minutes after being planted. Don't try to harvest the pumpkins as soon as any become available - let them grow, and then you have a chance of growing a big pumpkin. The graphic of the crop doesn't change when a big pumpkin is available, you'll just get one when you harvest them.
You can eat the pumpkins, both regular and the large ones.
The chance of a large pumpkin is about one in every 8 seeds planted. Once you get it, use the pumpkin carving kit to carve it out. There are 9 different styles available.
There's a forum thread related to the pumpkins already open:

Temporary issue: the pumpkins display that it's a temporary item, and they are, as they would decay 30 days after being picked. I'll remove the temporary-ness, since the seeds were priced with consideration that the pumpkins will be permanent.
(If I remember the reasoning behind this when we were making this quest, the pumpkins in real life usually rot during november and next year we grow and carve new ones. Perhaps to make it compatible with the old idea, there could be 2 types of seeds - the regular harvest-quest ones that make temporary pumpkins, and these bought ones. Well, since the seeds being sold on the NPC is a temporary solution, perhaps all pumpkins in the future years might just be regular, decaying after 30 days, but maybe there could be a jack'o'lantern-preservation-kit sold for the halloween supplies tokens).
