Looking For a Shiny Stone?

Well look no further! Iron Island is famous for this little artifact and it just so happens to be easy to find. Hidden inside a cave, high up on the exterior of the island, they are known to be found. The difficulty is getting there. If you had a Pokémon that could use Rock Climb, this would be a breeze. However, you notice that there is a couple of Togetic and Roselia that are playing about around said cave. This might not be as easy as it looks.

You must have access to HM 08 Rock Climb in order to attempt this challenge. If you wish to tackle this challenge, say so in the new thread you make when you enter the Island. This challenge is repeatable.
