H'lena: Lawns are patches of short grass some human societies in my world, and some others, plant around their houses. These societies don't believe in gnomes, so they build artificial carticatures of them and use them as decorations for their lawns. They made something similar after creatures like me. *pauses* Not sure if rainspouts are a step up from house decorations.
Che: The gnomes I've seen are short, ugly creatures that sometimes raid people's yards. I can't see why the humans you know would like to make decorations out of them.
A'melie: ...Never heard of them.
