Make toys out of them.
I have found myself with a large number of mushrooms. And, I hate to eat them. I found something great to do with some of them. I put a few in different muffin tins & gave it all to Peyton to play with. He loved it. It kept him busy for quite a while. He loved pulling them apart. He didn't get the transferring from tin to tin. But, he still enjoyed the game.
