I'm trying to catch a shiny Skitty on Route 4 (the only place to catch one) via the chaining method. The problem is that the chaining method requires you to use the Poke Radar which doesn't seem to work with flowers (flowers seem to act almost exactly like grass in X/Y), and Route 4 just so happens to have no grass at all.
So, how can I chain if the Poke Radar doesn't work in flowers?
