Well lets find out. I think thats the best way to solve any mystery possible, to take theories and try them out and if they dont work then we dont have to worry about it. Can we get a hacker to find that out for us?

I must've watched that opening scene a hundred times, and I know for sure that where Dingpot is in the beginning is the same room as the yellow transporter pot and the extra life right after the Furnace Fun mini game.

The door was just there as a theatrical aid, but it is the same door model as the one in the beauty machine room. Maybe that's why the one isn't connected to the wall...

Klungo comes through one of the green knocker doors in an early cutscene, so there's a short path behind the door on the right (I think).

Nothing at all behind the other one though.

There's a short path on the door on the left as it's occasionly open like in the game over scene, Klungo walks out of it.

I've tried that on my rom before. There is nothing up there. You can't even get in the tunnel.

ok Ive uploaded the savesate to my Inventory *see sig* in my Treasure Chest Section, its 1.5mb and is for project 64 users only, im not sure if it works for other emulators but i doubt it :(

Regarding the beauty room door:

Been there using a code that rotated all sprites (even doors) by however many degrees on the x-axis. Nothin' at all but where the Grunty sprite must've been in the first of the game (kinda like a small walkway/platform right after the door) and if you go too far after that, darkness.

Anything else I can check out? lol

ill look into something too if anyone wants =3

IMO, Mad Monster Mansion has alot of hints to SNS. Captain Blackeye and all the pics. Even two the SNS eggs are there. I suggest looking around MMM some more. I remember when I was on top of the big organ in the church the SNS text changed to orange.

ill investiogate MMM also the end credits show the phantom portrait monster and the portrate shown is blackeyes, could be a small clue.

EDIT: I just thought about something in MMM, in the church on the organ is a music book with an open page, after completing motzands puzzle, you still get to play the organ, what if we tried to play the notes on the book on the organ it could unlock some secret about SNS. Trouble is im not so good at reading the notes on music books, i never did well at music, but if anyone here knows everything about music, could they tell us the actual notes on the book to be played.

Thats a screenshot of the book.

From what I can discern;
G, A, G, A, A, B, B, D, F
D, A, D, A, B, C, C, D, E, E

G, A, G, A, A, B, B, D, F
D, G, D, E, F, E, E, D-

I have no clue what's going on in the Bass Clef lines...
Also, I'm not sure of the accuracy, but you seem to be on to something here...

That's just the Mad Monster Mansion theme. It's a bit hard to make out, but when you know what you're looking for, it's clear.

^ All the same it could unlock something maybe another tune or something, it's unlikly but possible. I don't really know what i'm talking about but with the RSA, i take it that when you try and warp there it freezes is it possible that it's by chance that it crashes and by chance that it works because i think it's the only thing that we really have to work with.

By the look of things that's just the MMM theme. Of course it might unlock something, you never know unless you try.

The church organ plays random notes on hitting it, though. Well, they're not actually entirely random - it actually plays the current note the melody of the MMM music is on - so you can do strange unisoned harmonies with it, if you like. :p
