Very nice little short, a bit happier ending than your last child.  
You say he's casual in the first couple paragraphs?  Like relaxed?  Since hes still dressed formally.
I don't know if I would use motherfukker or a5shole, since its coming from the mind of a younger kid.  Also most noir movies were made in the time before profanity was acceptable.
IMO I would have another switch back to noir style, even if its right at the end, maybe a quick VO or something to that effect.
Maybe add some basis for his dream, like maybe after he wakes up his mother and father come out of the place, they were the man and woman.  
Good script though, definately a fun idea.

Hey Michel, fun little story.
I agree that maybe changing the kids name would be a good idea, just to keep it as your own thing.  
I think the only issue I have that hasn't already been covered would be the timeline of him bumping his head.  There's never a moment where he falls or almost falls, or a point where the fantasy would start.  Obviously you don't want to make it obvious to the watcher until they are looking back or watching it again.  But in the reality of this script, when does the fantasy start?
also not sure about the title, it doesn't seem to be in the same mood as the rest of it.
Other than that I quite liked it.  It kind of shows you the seriousness of a kids imagination, where life and death are always at stake.  Good luck finding a kid that could portray that.

Ophelia and jackx, thanks for the reading.

I get what you mean. I wrote that short about 20 years ago in French. Clavin & Hobbes were not as famous as they are today.

The story starts when he jumps through the window at the beginning of the sequence in the swimming pool. That's where the tramp will find him at the end.

Spash! stands for the swimming pool.

Believe me I have a living example by my sides...
