@Anmirla As of now, the only gnome I've never had is the hip hop gnome. I've had more spring gnomes than any other kind, except for the horse gnomes, and I agree with you about those voyeuristic rabbit gnomes. They're worse than the peeping tom mail carriers.
@Auroraskies That's the wiki page I referred to, but I guess I should know enough to not take it as the final word on gnome behavior. It says that only the Mysterious Mr. Gnomes can have families, I know from experience that isn't true. All of that type I've ever had first appeared as babies when I only had other kinds of gnomes to parent them.
