People say it has something to do with celebi, saying you then (if you have National pokedex) can catch celebi with a GS ball (meaning go to the shrine and put the GS ball in the shrine in Ilex forest) Celebi will appear (as what people say) at lvl 30. if it is caught and first in your party, in ruins of alph instead of unowns its celebis
This is a complete Lie.
Nothing that I know of happens, because I havent, but talk to the guy who gave you the Unown report, maybe it'll do something.
Chat with our AI personalities
nothng happens
The tunnel on top the ruins is accessible.The tunnel is where you catch the ? and ! Unown.
You have to catch all 26 unown and talk to the scientist a few times for additional pages.
Nothing happens, except the fact that you have many Unowns. ~Katie
If you catch 26 Unown in Pokemon Diamond, go to Ruin Maniac Cave. He will be waiting inside for you. You can catch Hippopatos in the cave, along with Geodude. Go to the end of the cave where there is another entrance. Go through, and when you get inside, you will see a writing on the wall. It says, "?!" Those two Unown are in there. Capture them. You now have all the Unown.
