> Corn / Grain

Well, the problem is what it should be good for. If we're going for actual farming, we are talking quite a lot of time investment. That must have powerful end results in order to be worth it. Otherwise it won't be compatible to other game elements and will end up as a mini-game again. Just healing Clonks probably won't cut it...

Is that a bad thing? I don't think we should put too much effort into forcing complexity into everything. We could go the "gold statue" way: Make gold bars have quite a bit more worth. I actually like the proposal for giving the foundry more stuff to do alone.

> Fungus / Mushrooms

Hm, we already have crystals for the "magic" part, and I doubt we'd want to drop it. And the food thing is already weak enough as it is, we don't need another resource filling that role.

Hard-to-aquire fuel? Hm. It would have to burn for a long time to make it worth all that drying...
