The last two Unown are located in the hall entrance.
You must solve all four of the picture puzzles and solve all of the word clues to get to the four hidden rooms (you will need to have Ho-oh for one of the word clues). You also need to catch all 26 of the alphabet Unown.
Once you have done that, you will need to talk to one of the researchers in the Research Center. Keep talking to him until he tells you he has nothing more. Then go into the hall entrance and look at the writing in the middle of the back wall. The researcher will show up and talk to you. You will be taken back to the Research Center.
When you return to the hall entrance, ! and ? Unown will appear.
First, you must capture all the other Unown and enter all the hidden rooms in the back behind the puzzles in the different chambers, then, talk to one of the guys inside the house outside. You have to talk to him each time you solve the puzzles.
Go back to the main entrance of the Ruins of Alph directly left of the house and he should be in there investigating the walls. There should be a spot where you can press A at and it should open another room. That is where you can catch the last two Unown.
Also, to reach the last two puzzles: you have to go through Union Cave. Take the ladder where the Firebreather is and Surf across the water. There's two paths that'll take you to them.
And to access the hidden rooms: you have to do what it says when you press A on the back wall;
-Use an Escape Rope on the wall behind the Kabuto puzzle that says "ESCAPE".
-Use Flash on the wall behind the Omanyte puzzle that says "LIGHT".
-Use a Water Stone on the wall behind the Aerodactyl puzzle that says "WATER".
-And put Ho-Oh at the front of your party at the wall behind the Ho-Oh puzzle that says "HO-OH".

Mewtwo can be found in the Cerulean Cave in HeartGold.
no you dont all you have to do is get a game shark or firered or I think leaf green and there is more than 26 unowns i have found two more When I beat the elite four before i had found one of the dogs. So I don't think that you have to catch any of the unown for them.
the last two unknown are supposed to be in the hall entrance after you catch the first 26 and complete every puzzle.
No they are not, braille and the unown are two different alphabet systems.
You can't without cheating or using action replay
You need to transfer Kyogre over from Pokemon Emerald/Sapphire, or trade Kyogre to your game from Pokemon HeartGold. If you trade the Kyogre to your game from HeartGold, you can talk to Professor Oak with the two of them in your team to get the Jade Orb, allowing you to catch Rayquaza where you found the other two.
they should ALL be on top
There is no such thing as "island two" in HeartGold. There are two islands in the game. Those islands include the Seafoam Islands and Cinnibar Island. None of them, however, are labeled "island two."
