The cheat for the gnome is Circle L1 L2 R2 R1
It works. I do it all the time. & The gnome is dressed in blue. He's about 2 feet tall [ In the game} and he doesn't move! Hes like a garden gnome. He's always around the sides of the districts. Oh yeah, and he sparkles. =] You'll hear like a moan or a "hmmm" sound when you have done it correctly. When you do a other cheat like unlock all socials, you click him and you select the cheat. ^^
