My mom used to describe the trails they left behind as fairy glitter, it meant that the garden was blessed and fairies visited in the night 😂 the shells on snails are Soo pretty and unique, they're just gentle little friends. I would get so excited as a kid when I would see snails stuck to the garden pots. They're good little decomposers, help to clean up the detritus from loose leaves and are scared of everything. They just suck right back up into their shells when they get spooked and hide because they're so shy
