heres a pic.

Yes, you retrieve the snake coin from a baby carriage in the pool. I don't yet know why.

I think to understand the significance of the pram you'd need to know the symbolism of the snake coin. I don't know what the coin itself means, but if, for instance, [spoiler]it represented Maria, then the pram could be seen as representative of her "birth" which would be occuring at about that time over in Heaven's Night.[/spoiler]

The swimming pool is empty, resembling the empty life of a man who has lost his wife, his happiness, and a good portion of his sanity. The carriage symbolizes the hope he feels, the hope that drives him to follow the letter into town. This item of hope is guarded by a group of monsters, symbolizing the dangers he must face before he reaches his goal. Upon reaching the carriage, he finds a coin inside, adorned with a snake, which perhaps indicates that James will find what he seeks, only to be met by a dangerous secret (Room 312).

If that's not enough overanalysis, I have another: The carriage symbolizes Maria: A carriage is designed for a baby: New life, new start, a birth (from a wish, hint), but it contains a snake, which in the Bible carries loads of metaphorical weight. It is a serpent who deceives Eve to eat of the Tree of Knowledge, leading her to learn of unpleasant things and be ejected from Heaven (possibly the shattering of delusion? A reference to Silent Heaven?)

Hell, you can take this to be a double-strength indicator of the Leave ending: Not only will eating of the Tree of Knowledge lead one out of (Silent) Heaven, but the pool is conspicuously empty. On top of that, the reference to Maria being the Snake, and the connotations that Rebirth is not desirable (the symbol of birth hiding the snake/Maria (the snake) being reborn repeatedly)--

The whole god damn thing is a huge-ass neon sign that says LEAVE ENDING.

Good night, everybody.

Wow, thats an amazing theory AITT. I Prefer the second theory much more.

A snake is born from a wish. I beleive the pool represents james empty mind. Whether it used to be full of his sanity or it used to be filled with thoughts of happiness. Either way those two things are gone in one way or another.

Considering James has not even met Maria yet. It leads me to believe that the carriage represents the new beginning he beleives will have with Mary if he finds her. This time she will not be sick and they can finnaly be together the way he wanted her. But instead he finds a snake, Maria...

I think the carriage is simply a homage to Rosemary's Baby. What do I know?

The answer?

Rosemary's Baby is about a woman used to mother the devil. The devil, as alluded to by Ryan, is represented by a snake in Genesis. The snake coin is in the baby carriage. The devil is the baby in the carriage.

Could it maybe just be that there's no significance behind the carriage AT ALL, and that the creators just decided to randomly place it there with a snake coin and some monsters? I mean, not to sound like a dick or anything, but not every single little thing is going to have some significance. Then again, maybe it does play some roll within the game. I duuuuuuno. I guess someone just has to be a little sceptical about these things. :>

Great theory, Alone in the town & MMY.
I'd go with Rosemary's baby as well.
Maria could also be symbolizing Lilith imo, who in some depictions appears as Adam's first wife. Most of her depictions show her with a 'snake' around her waist. An as you know in some eastern cultures, two snakes (posed like an inverted 8.) symbolize 'infinity'. Lilith is derived from the hebrew word "Layl" which means night & nucturnal (Heaven's night?).
So I'm gonna relate this theory to the "Maria" ending, in which [spoiler] James is supposed to repeat all the expereince as if nothing has ever happened, since Maria starts coughing like Mary. Therefore in this particular ending James has learned nothing & has to repeat the events till 'eternity'.[/spoiler]
The carriage & the snake represent a "rebirth" (rebirth of Mary through Maria) which is in fact a deception (Lilith & the snakes around her) to make James go the wrong way, IMO. (ie. exiled from Heaven)

Pretty good theories in this thread.

Concerning the Snake coin being Maria:
An Oroborus, which is a snake eating it’s own tail, is a representation of the cycles of mankind destroying themselves over and over again -and relating on what Returbuliz stated: [spoiler]A lot conclude that if James chooses Maria, which has been implied as the snake here, then it’s James presumably continuing the cycle of the situation he went through with Mary all over again when Maria “coughs“.[/spoiler] He is still choosing a life that is empty, still clinging to it, only to be deceived and inevitably realize his own self destruction all over again.

^^^ that sounds pretty good I like that one.
