Er...I...um...what‽

It’s true! I would collect them in a pail from the tidal pools as a child. I would crack them open with whatever I had available and eat them, and the halves would still be running around on the ground after I discarded the rest.

The parts of urchin, the remains, they would skitter around and bunch up in one corner of the yard trying to get away like they didn’t realize they’d been eaten yet even though there was nothing left inside.
