If you swim out into the ocean in the Driftwood area, once you hit the boarder where you can't swim out any further if you tilt your camera to look down into the water there is a Lionhead Studios logo on the sea floor.

During the Hideout mission of bowerstone when going to capture Nigel Ferret. You will come across a room with a silver key. At the far end of the room there is a path around the boxes to the other jail cell. In the cell is a hobbe worshiping the companion cube from portal and on the table next to the cell is a cake.

In the graveyard in Mourningwood there will be a tombstone that reads "It's dangerous to go out alone. Take this". Your dog will bark and start digging right in front of the grave. Your prize? A powerful "Toy Sword".

In Millfields, below the graveyard, you will find some graves. Read the first three on the left: Walter Coen, Stabbed in broad daylight. Jeffrey Coen, Burned at sunrise. Theodore Coen, Shot in the dead of night. There are statues hold spyglasses around Millfields. Go out of that little grave area and you should see a statue standing ahead of you. If you read it, it says: Theodore Coen. Wait until midnight than keep shooting the statue, it should glow for a second and you should hear the sound of someone dying. Now head to the gazebo in the middle of the lake and look down the bridge that leads to it. You should see the Jeffrey Coen statue. Equip the fire spell, wait until morning then keep shooting it at him. He should glow and make the sound of dying. For this last one, go to the Demon Door and you should see another statue. This one is Walter Coen. Wait until noon and keep hitting him with your sword. He will do the little glow and sound of death thing, then you will see the pull right trigger prompt. Pull it to see that an egg appeared in the gazebo! Pick it up to see that it is the "East Hare Egg". (The East Hare Egg does nothing, gives you nothing and will not appear in your sanctuary. It is just for a little fun.)

There's a quick, easy glitch that allows you to dupe gold or anything else. You just need a 2nd controller with a 2nd character logged into your game. Then use player 1 to "gift" player 2 whatever you want to dupe, then leave player 1's sanctuary. Have player 2 go into his sanctuary and find the gift. Now have him reject the gift to send it back to player 1. Immediately have player 2 leave his sanctuary then immediately drop him from the game. Now player 1 has a rejected gift in his sanctuary and player 2 will not be saved, meaning when you reload him, he will also have a gift the game didn't save as being rejected. Dupe! You can dupe up to 100k gold at a time using this.

Most in-world creatures will only pursue you so far - move away from them till they stop. Shoot them with Ranged weapon and they won't come after you - may not work with ARENA, or Main quest events - Great way to upgrade ranged weapons. Stay out of their attack range, snipe them easy!
