the ds,game cube and the nintendo64

theres a new metorid game out for ds but on the prime one it tells you about the ds before it even gets built and also about the game.
on the nitendo on mario 64 i got told if you stare into the glass you turn into lugi but it dont work a few years later the ds mario comes out and i tried the trick in a ghost level and you never gess what happend .... mario turned into lugi.

Not to sound like a mother hen or anything but, this thread really should be on BTS in the V-games section.

Those are called "easter eggs" becuase they are like little suprises, all games have one or more of them. The best one I can remember was on Heavy Gear II, around Christmas time all of the "Gears" wore Santa hats, I got a good laugh of this one.
