When you get to Rivendale go up to Gloin who is sharpening an axe. Give him two crams. A light will apear above his head. Then give him a lembas after which he will say "Then I must help you.".
Now go in to see uncle Bilbo. Normaly the fire in Bilbo's room is not lit but now it is and there is a light above it. Go up to the fire and press the X button.
You will have a choise betwean Frodo, Gandalf, and Aragorn. You can go into the secret level as many times as you want with any of the characters. But you must do it all before leaving Bilbo's room since once you leave the room you can not go back in.
Make sure to save your game befor going in as Aragorn. For some reason it always glitches when I go in as him and I end up having to restart my Xbox. Also the two chests in Bilbo's room.
From one you will get a mushroom. From the other you will get either an ancient tomb or a bottle of spirit. These are for Gandalf. After leaving the room you can go to Gandalf and give it to him and he will say to you "Mellon" which is the secret word you use to open the gates of Moria.
At the troll shaws just befor you get to Rivenale, when you have to get Frodo through all those goblins and have to keep giveing him athelas so he does'nt die from poison, find the three stone trolls. Go to the middle one and start striking it with your sword. Keep doing this until a light shines above his head. Then give it a Beryl Stone. It will then give you two more back.
When you get to the Inn of The Pranceing Pony jump up onto the front desk right under the sign. Jump up onto the sign and pull yourself up. You will have popped your head through the cieling and into the room above where there is a cram.
When you go into the Green Dragon Inn go and speak to rose up at the bar. Keep talking to her until she asks you to retrieve a cask of cider. Do this and she will give you a set of silverwear as a house warming present. You can use the silverwear at the mill up in the loft where there is a mound of dirt. Face the mound. Then scrole onto the silverwear and push the black button. You will get elf shots (which are great because you can hit enemies from realy far away). You can do this three times. Then if you want more you can exit the mill, then go back inside and do it all over again as many time as you want. Then when you've gotten to The Inn of The Pranceing Pony you can give the silverwear to a hobbit named Nob who will then offer you a potion or arrows. Just make sure you do this before you talk to the in keeper.
While in Hobbiton go to sam's house.Go over to the bed and see the dog. Then go to Bywater and speak to Angelica. Keep talking to her until she askes "Have you seen my little doggie? He's no where to be found and He's ever so late for his bath." She will then give you an egg. Take this egg and return to Bagend. Go into the kitchen where there is a black pot on the counter next to a tea pot. Notice that Frodo turns his head tword it. Face the pot. Scrole onto the egg and push the black button to put the egg into the pot. Then put in an Athelas plant and you will have made yourself a potion.
There are mushrooms hidden in the leaf piles you find all over Hobbiton. If you throw a fire cracker at them you can get two mushrooms. It even works on piles you've already disturbed. Make sure you aim at the base of the pile or it will just go through it.
