Game of Shrooms is a once-a-year, worldwide art-N-seek event created by Attaboy. The next Game of Shrooms happens on June 10th, 2023. On that day, artists from all over the world hide their original mushroom-themed artworks in public places. Then, they give hints (often on social media) for others to find AND KEEP!

There appear to be several hidden in Ireland.
