You could basically just use the same routine.. without reversing it.

Just a thought:

What if the four eggs we're supposed to get are the four that aren't shown to us by Mumbo?

A different angle to view it at! However, Banjo speaks after collecting the pink egg, the ones with text following their collection are most likely ones that would be intended for SNS. (Although I am still not convinced, I think all were needed).

Banjo speaks whenever the first egg is collected, regardless of colour.

Oh my dear you have to learn a much here.

Is that certain?

If so, that further leads me to believe all the eggs were originally intended for collection.

Something is said after the pink egg is collected. What about the others? I am sure he says "Oh another one of those special eggs". He says two comments after collecting eggs, right?

One from collecting the pink and one from any of the others?

Someone confirm please.

Hmmmmm, i'm almost positive it's with any egg.

Though if I rememebr rightly the first egg I got was in fact, the pink one...

Yeah I got them in the order that mumbo showed me then as for the others I remember it like this:
Cyan
Green
Red
Yellow
If my memory's not completely gone Banjo made comments with the first two eggs I obtained then was quiet with the other 4. I honestly can't remember if he says anything for the Ice Key.

It's either him or Kazooie that says something about getting the Ice Key (Pretty sure it's Kazooie), either way there is text there.

Yes, it is Kazooie that says something about the Ice Key, something to the effect of "wow, a giant ice key, we should have this for later" .

What happened to the 'start debugging/reversing the game and find out' thing? I'm serious about this. Let's give it a shot! Can't we have a deep aim conversation about it?

What's that then?

I am not sure I know what that is.

T_T what, what is, exactly? Reversing stuff?

I've a few things to say, I havent been here in a few days and I want to reply to some of the confusion about the eggs themselves
First off, banjo speaks after the first 2 eggs, regardless of what order they are collected in.
Secondly, thats not a bad idea, we get the eggs mumbo doesnt mention... Can someone try that? It never made much sense that he only mentions 2 anyway, seeing as BT itself has the yellow as well....
Thridly, MarcX's idea is probably a good one, but I cant help feeling that if it WAS that simple it would have been tried already... We should have an AIM chat about it some time, it would be easier...

Yes, someone should try getting the items not revealed by Mumbo first.
