Giant Pumpkin

Now and then a Pumpkin grows into a giant as it ripens: 1 in 150 times, on a tile that can start one. Only some tiles can: 4 on a 4×4 crop patch and 1 on a 3×3 crop patch.

It covers 9 tiles, clearing whatever grew under it, and ends the seed's harvests. Click it 12 times to harvest it: it bursts into 36 crops of Pumpkin, but pays no spare parts.

In October it grows as a giant jack-o-lantern, facing either way at random.
