Since i dont know which one you are talking about ill give you all three and you figure it out from there.....
Worry about that in just a minute or so: for now, head further south
and fight the Painter with his Camerupt L65. Just south of him is a
Razor Claw — an item that boosts the user's critical hit rate, but
also evolves Sneasel into Weavile if it levels up at night while it's
holding the Razor Claw — and also Gram 2, which you'll want to deliver
to the girl with the Wingull.
Take that back to the girl, talk to her, and she'll give it to her
Wingull. That leaves you left finding two more packages. Go back down
the steps and talk to the old man from earlier that I told you to
remember. He'll give you Gram 1. Before you head back to the Wingull,
head further south and pick up the Gram 3 from the Parasol Lady that
didn't battle you earlier on.
