First the squash stem taken with my point and shoot...

Then the "prickers" in my finger, also with my point and shoot...

Then the prickers at ~ 1.8 X Stereo constructed with Zerene Pmax from ~ 200 image stack

Then prickers at 10 X Stereo constructed with Zerene Pmax with some substacking to help remove transparency of overlaid detail.

The blunted points probably ended up in fingers or gloves when the squash was harvested.
