I know that I am correct on the picture Puzzles, and the Letter Puzzles, But the letter Puzzles may be in the wrong order, if I am mistaken.
The Ho-oh Puzzles are definitely in the 3rd Room, which you will probably not be able to go beyond, without until you catch Ho-oh,
weather you catch him as soon as you defeated the Kimono Girls in Ecruteak City
or
after you managed to get his, I think, Rainbow Wing, in Pewter City after you were in the Hall Of Fame.
In the Unown cave, you can battle Steven after you catch all the Unown including the punctuation ones. He will be at the top of the cave in the Ruins of Alph. Make sure you have a few level 100s or you will most likely lose to him.
114 is Unown. This is how u catch it: Go to Solaceon town. Go to the right and jump over the last three ledges. The cave u come to is the unown cave. CATCH ONE! No other trainers have Unown and they only appear in that cave.
In Aegis Cave.
in that cave in solaceon
in the cave!
go to solaceon town and walk to the right side of the town until you see a cave go in and all the Pokemon in the cave is unown.
in one of the cave rooms in the cave right of solaceon town
first go to celistic town.Then go to the east. then go down the 3rd ledge and into the cave there, in that cave you can find unown
Unown Cave doesn't exist in Pokémon Emerald. Unown only appears in the Ruins of Alph in Pokémon Gold and Silver, including their remakes, as well as in Crystal. It also appears in Tanoby Chambers in Pokémon FireRed and LeafGreen, and in the Solaceon Ruins in Pokémon Diamond, Pearl and Platinum.
There is no "and" unown on any Pokemon game. Only A-Z, !, and ?
they are in a cave near snowpoint
Without solving the puzzles you cannot battle the Unown in the nearby cave (the one you fall into after completing the puzzle)
