Snails are pretty amazing, from their wiggly eye stalks to the way they carry their houses around on their backs. Unfortunately, they're also pretty small, and as a result, they often get stepped on. Their camouflage helps them evade predators in nature, but in areas where humans are the majority of the animals, a little visibility might actually help.
Not only does it make the snails more visible (and less likely to be stepped on), but it also adds a bit of fun to the general surroundings.
