Ratchet and Clank 2 Easter Egg - The Insomniac Museum

The most important part of this egg is that you get far enough in the game to reach "Silver City" in "Boldan." There are two real ways of doing this. First is to wait until 3 a.m., then as soon as you reach Silver City, if you get to this bit, go to the part where you have to go either left or right at a forked section. You go left here and kill everyone in the area then you go on top of the water fountain. You will see a small circle shaped floor thing that looks like a teleporter except without the spires. Wait until the giant clock chimes 3, then quickly press triangle you will teleport to a room (beware that you press triangle while the clock is chiming). In the room some enemies will spawn; fight these all the way to the teleporter at the other end and press triangle to activate you will go there.
Another way is to go straight from your ship and ride the elevator up, then go up the ladder. Ride the rails to the construction site. When you are right BEFORE the construction site hit the electrical pole of the FAR left and glide down to the lone buildings. Face almost parallel with the rails and you will see a building with a clock on it. Go to that building and go around the left of it till you fall through the concrete. Apply a strongish weapon and then jump up after going right for a little bit. High jump then take out the enemies who are guarding the translocater. When all the enemies are defeated take the translocater to a planet called "Burbank". NOTE does not matter what time it is. Welcome to the Insomniac Museum.

Here is a planet called Burbank. Inside will be the museum. There will be exibits of all the missed out and interesting things from all the ratchet and clank games and some interactive exhibits as well. Also if you go all the way to the back you the Electrolyzer to open the huge garage doors. Once outside go right around the edge to get to the gravity tower. To get onto the roof of the museum go to the vertical tower on the left side and go all the way around until you get to the last loop and jump onto the skinny little ledge that it has, and if you jump toward the roof you should barely make it. (Don't try from globe thing it doesn't work). Also on the roof is a huge hammer, and I don't know what it does.
