Today, for example, we look at anthropomorphized vegetables. That's right.
One of the running themes of Unglued 2 was going to be anthropomorphic vegetable creatures that gave poison counters (because, you know, vegetables -- poison). Take a look at the art of some of these tough veggies.
The poison-veggie theme was not carried explicitly into Unhinged, but you may detect a vegetable here and there in the art of certain Unhinged cards -- which indicates art that was carried over from Unglued 2.
