what's all this about 4 eggs? where did you get this idea from?

See 1st post.

Well solved like what actually happened to it.

they'd probably be known from Banjo fan to Banjo fan....

but that wont happen anyway, unless Rare specifically tells one mortal... and then the spill the beans to everyone

Actually, there are several mysteries in the levels list (check the GS glitch topic):
That weird spiral mountain clone we found, where it just spins past you, for a start
Then, in memory, search for the word "secret" and you'll find a bizarre table, with blank lines above and below it, which says
SECRET ICE SECRET BEACH SECRET EGG SECRET CELLAR etc

Cool! But for so many years, people have been hunting for the explanation for SnS. If someone did actually find the solution to it, would they be like, worshipped like a god or something for solving this great mystery?

not worshipped, but theyd definately be known!

was stop and swop going to include grabbed by the ghoulies?

nope, Nintendo products cant connect to Microsoft products anyway it isnt natural

Grabbed by the Goulies was originally for N64.

Yeah but it wasn't going to be part of the banjo series, was it?

What i believe is that the three sketches are.... Sandcastle island inside (From an aerial view), The Ice Key platform with the ice key in the middle (from an aerial view), Gobi's door to the blue egg.

EP... just.... no.....
The board in GbtG has this picture on it:
0¬ + (?)(?)(?)(?) = ???
and below that it says
1: Collect ice key
2: Collect 4 eggs
3: open secret level

.....................

I thought you knew everything.............

I was talking about the pictures above that equation.
And the assignment is to the right of the equation.

Christendom, Judaism, and even some Hinduism. :p
