moominesque oak creatures

I'd never seen an oak ball, or 'oak apple' until pretty recently. Growing up in Tennessee, I'd never noticed them so when I found some on a walking trail I had to collect a few for the novelty factor. I wasn't sure what to do with them until my 5 year old dug some holes in one and we both thought they looked skullish. So now, we're collaborating on a series of creatures based on the oak apple skulls. Here are our first two, 'the colossal twin' and the 'pinch snoot'. Moominesque!
