Snugglemi Snackers Avocado

I was in the middle of making breakfast when my friend, who for some reason was in my kitchen at 7am, asked me "What's that wooden ball in the center of avocado?" Reeling from shock, I immediately threw them out of my house. I mean, how does someone not know what an avocado seed looks like? But more importantly, why were they in my house? Is there more to this story? Probably.
