Years back we had them at my dads cottage in Michigan...he called them “monsters” and when we visited, at night he would give my kids (5) each a shaker of salt. They went monster hunting and the next day showed dad the ones they killed...there would just be a pile of slime where once there was a monster...got 25 cents for each one they killed. They are in their 50’s and still remember “monster hunting”. Of course they also had flashlights.
Cute. Nice memory. Except for the slugs, of course.
