Ratchet & Clank 3 Easter Egg - The Second Insomniac Museum

When you get to Metropolis, start up your PS2 without the disc in. Then turn the time to any time between 3.00 and 3.59 A.M. Insert the disc and load your game. On Metropolis enter the first room and take out all the enemies. Then instead of going through you may notice there is a ledge on the left and right of the room. Jump up to the left one. There is a window. Break it with the wrench and jump over the gap into the next room. Take everything out. Again you will notice ledges on the left and right of the room. Jump up to the left and break the window. There is a teleport which will take you to the new Insomniac Museum level. It is very cool. I reccomend the Special Edition Vid-Comic.
