By the time you take the last step and come to the end of the spiral, it's likely that the irritation boiling behind your eyeballs can be compared to the heat of the Vesuvius eruption that took out Pompeii.
Or maybe not. Maybe you're just fine with it all.
In any event, at the end of the spiral is music stand. On it is a piece of sheet music.
Seems you have what you need to play on the pipe organ.
It's apparently the theme to
My Humps by the Black Eyed Peas. You end up having to play it three times on the organ before that damn door swings open.
Now that song is stuck in your head...
New Map!
And beyond the musical door is a new rom. It looks like another puzzle chamber. Great.
The walls and ceiling and floor are made of glass. The high density kind you walk on without worrying about it. Under the glass are lots and lots and lots and lots of clockwork gears. They are set up in elaborate arrays that seem to be accomplishing nothing.
No. Wait. They are accomplishing something. All the clanking and tapping and whirring are creating a distinct rhthymic and muscial pattern. It's like you're inside a giant music box that's all wound up. And the music box is playing
My Humps.
Over and over and over and over again.
There's another vault style door leading further on. Of course it's locked. Too durable to pound through it? You know it!
There are three cogs on the doorway with gaps between them. Apparently if there were smaller cogs stuck between them, then the array would turn.
Oh yeah. Those piles of cogs in the last room. Now you get it.
Of course there are thousands of cogs in those piles.
There are clues. Each of the cogs on the door are labled with numbers. From left to right they are numbered
18
14
12
And all the cogs in the piles are numbered as well. From 1 to 500.
So you seem to have to find the two cogs that fit the sequence you guess?
