Not quite on topic, but I have a great slug story.
Back in the dark ages in my first year of teaching, the boys in my primary school class got fed up with the cute furry classroom pets that the girls all cooed over. When I asked them what pet they would like to see in the class, they answered: "Slugs."
They had a plan ready to share: they would get an old fish tank, fill it with leaves "and stuff" and put a few slugs and snails in there. They said they would be in charge and I wouldn't have to touch any of them. I was extremely dubious about this, but being young and still unaware of the short attention span of 10-year old boys, I gave in.
A day or two after it was all set up (gross!) I had to go on a course, and forgot to prime the poor substitute teacher. The next morning I entered the classroom to find........ yes, slime, slugs, snails EVERYWHERE. When the boys eventually came in, they admitted they'd forgotten to put the lid back on after "giving them some air" - they'd gone out to play football and left them to escape.
If I close my eyes, I can still see the carnage. And the salt. Lots and lots of salt.
