White Pumpkin

Unlocks once you've harvested 540 Green Grapes, 440 Zucchini, 480 White Beetroot and 170 Purple Potato in all; unlocking it is then free.

A seed costs 90 spare parts and grows for 14m 40s (11m 44s on fertilized soil), needing water 11 times on the way: it stops growing until it's watered. It gives 19 harvests, growing back from scratch after each one.

Each harvest is one White Pumpkin and 24 spare parts: 456 from one seed, 366 more than it cost, over 4h 38m of growing. In a Biofuel Converter each one is worth 18 biofuel.

On some patch tiles a ripe White Pumpkin can grow into a giant one instead (1 in 150), worth four crops for each tile it covers but no spare parts; it ends the seed's harvests and clears what grew under it.

In October (going by the computer's clock) it grows as a jack-o-lantern instead: each tile planted gets one of 6 carved faces, picked at random, and the crop shows as a jack-o-lantern everywhere else too.

A Reaper chip can improve its grow time, watering, harvests, biofuel or earnings.
