The only thing to do in the tanoby chambers is catch the Pokemon Unown.
they spell the alphabet and maybe you get a rare Pokemon
The tunnel on top the ruins is accessible.The tunnel is where you catch the ? and ! Unown.
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.
Nothing happens, except the fact that you have many Unowns. ~Katie

Nothing happens if the unown you catch can be arranged to spell water.
Nothing special. They just spell out the alphabet, maybe you get a rare pokemon (;
once you catch all the unown something really cool happens its lik you either go and kick lugia's ass or catch Ho Ho and Deoxy's yo choice
Trade Unown from FireRed/LeafGreen, or if you used a gameshark for encountering this pokemon, trade from Ruby/Sapphire.
Nothing you just catch them that's it. Psst in the monean and viapois chamber you can rarely find a question and exclamation mark unown.
you can't get unown unown on Pokemon sapphire unless you trade from firered/leafgreen.
