When I was a kid (last week) we used to go down in the mud flats and dig for marine worms(sea worms) We got a can full and took them home. These worms are better for fishing in salt water than earth worms. We were going to go fishing the next day.
Usually we put sawdust in the can as it helped to keep them separated and I think it prevented them from escaping. We used to get sawdust from the butcher, back then they put sawdust on the floors of meat shop.
This time we didn't get the sawdust, and all the worms were missing the next morning.
No fishing that day,
I was devastated, happened 50 years ago and I still think about it.
