LittleBigPlanet 2 Easter eggs

Castlevania Easter Egg
In the beginning of the level "Lift Off" within The Cosmos world you will come across various Arcade Machines. The machine on the end is broken and a sackbot is trying to fix it, however if you hop into the controlinator seat and then press..

Up, Up, Down, Down, Left, Right, Left, Right, X, O

(the infamous Castlevania cheat from many years ago. Although X and O replaces A and B for obvious reasons)

.. the machine will explode, the sackbot will get electrocuted and run away and once the dust settles an 8 digit number will be revealed.
At this point nobody knows what that 8 digit number means but it must mean something right?
