Is this creature a pest that should be killed or is it harmless to a home and garden?
It's a snail, don't kill it.
Is that one of them mini-turtles? SO CUTE ????! Don't kill him, just give him a few tiny pieces of cheese to eat and he'll leave your garden alone.
Good for a garden, snails is among the fauna you want, along with but not limited to worms, ants, and praying mantises.
These people who are saying it's harmless or good have never had a garden. Snails will ruin your garden plants. They devour them just like bugs. Kill it before it starts multiplying.
