there is a item outside the cave you find unknow how you get the item and what is it cause it looks so impossible to get I tried to go every way to get it (it is the pokéball that is in the cliff with a hole to enter the cave)
You have to catch all Unknows A-Z to get to the item. There is a man digging in a cave if you collect them all he will be finished digging the cave, and you can reach the item.
