Day 27 of Toontober 2 is Ivy!

When the Great War finally ended, and farmers were able to return to their fields, their ploughs turned up a vast quantity of bullets and unexploded munitions. Around the world this quickly came to be known as the 'iron harvest'.

Fortunately, most of the larger relics of the war have been safely removed by now, though even now there are still exceptions. In this case, a bombed out land ironclad, which a local group of bandits have taken to using as a hideout. Although it no longer runs (And even if it did, getting it out of that crater would require a crane), the bandits are able to use it as a secure position from which to raid travelers and store their ill-gotten gains.
