A fun challenge for creature designers is to create a whole new being that is halfway between a human and something else. Mythology is full of composite creatures such as centaurs and minotaurs that combine parts of humans and animals. You can also infuse trees, vegetables, or manufactured objects with human traits.
Here are some designs for garden goblins. These started with a grocery bag full of sweet corn and ornamental gourds from a farm market.
The corn husks seemed like a logical material for their homemade costumes. I wanted them to look impish, so I also looked at photos of chimpanzees.
