Giant Pumpkin

A requires a 4 x 4 empty space in your inventory in order to pick it up. If you slice a pumpkin you get 8 Pumpkin Flesh and 8 Pumpkin Seeds of the same quality of the pumpkin. It is notable that pumpkins are the only crop not affected by the nature/industry belief slider.

How to Acquire
You must plant a pumpkin seed, wait for the pumpkin to grow to full size and harvest it (6 growing stages). Pumpkins take 5 days to a week to grow.

With the Pumpkin in your inventory you can right click the pumpkin and select "Slice". This choice will yield 8 Pumpkin Seeds and 8 Slices of Pumpkin Flesh (which are edible)
