Ask the Gnome!
Smurfette? Why yes! We helped her hide.
Gargamel is looking for her? Dear me, you better find her first!
She isnt near any of the schools in Helena. I sent her to one of the small creatures of Helena to help her find a perfect hiding place. I know Gargamel would never think of asking a mere insect. Go to the ladybug she will tell you where she went. Meanwhile I need to do some shopping.
