The pit of an avocado is a source of annoyance (and even a source of harm) for some consumers. But Irish artist Jan Campbell looks to the fruit’s inedible center for inspiration. According to Bored Panda, she carves avocado pits, that would otherwise get discarded, into whimsical characters based on Celtic mythology.

Campbell’s Avocado Stone Faces project was inspired by a meal she made in 2014. After eating an avocado, she felt compelled to hold onto the pit that was left behind. “It dawned on me that I was holding a substantial object in my hand, one with a lot of potential,” she wrote on her website. “It felt like a shame to just throw it into the compost.” A couple weeks later, she returned to that same pit and carved it into her first 3D character.

Since that first attempt, Campbell has recycled avocado stones into bearded figurines, miniature mushrooms, and playful pendants. She shares pictures of her creations on her Instagram page and sells select items on her website. Take a look at some of her most intricate carvings below.
