If you passed too quickly on Route 9, you probably missed the little Pincurchin. And for good reason, it doesn't show up directly in the tall grass!
It's part of the Pokémon that are non-overworld and in the form of an Exclamation Point when you run through the tall grass. Problem? His spawn rate is only 5% chance!
You will therefore encounter Cramorant more often, but do not lose patience.
