Interesting, to be honest my room is also done up like a ship, but in a differant style. The previous owners of the house had their father living with them in the basement, and he was a ship captain (differant style, more modern) who had trouble getting used to sleeping in a normal room, so the room was done up entirely in wood paneling, with the bed section built into a cubby on the wall (which is where I stick my mattress). Kind of cool for a spare bedroom, and makes it so I'm a bit less embarassed about being the quintessential "35 year old basement dwelling nerd" now that I'm disabled.
On a seperate note, I will say that I'm finding the current obsession with pirates to be a little disturbing to be honest. Kids have always liked pirates, but part of the entire appeal was that they were bad guys. It's sort of like a fascination with outlaws or whatever else. Today however I keep seeing all of this stuff about how being a pirate is all about freedom, and little more. A while back I remember reading someone's rant about how pirates were basically a bunch of seafaring hippies that kept getting hassled by "the man". Right up there with someone on these forums who once tried to claim that the colonists who came over on the Mayflower were a bunch of socialists who established a commune (having never heard about Carver or Bradford in school apparently).
Being a pirate was all about being a murderous thug who killed people, oftentimes quite sadistically (and doubtlessly enjoying the heck out of it), stole their stuff, and then sold it. We're talking massive atrocities here.
I think that the popularity caused by the Disney movies where you rarely see Pirates do anything really bad (and when they do it's glossed over, the worst bit being the very beginning of the first movie with the wreckage) has become sort of a problem. Even the "bad" pirates stop being really evil once they aren't undead anymore, heck the bad guy from the first movie becomes one of the heroes.
I don't know, I guess I just find it vaguely wrong for a six year old to be that interested in pirates and to consider it quite THAT kid-safe. It's the kind of interest that I'd think should be coming about years later like in the 9-11 range. That's the point where kids start to get a fascination with the morbid, pirates, ghosts, outlaws, and even seriel killers are not all that uncommon.
I think what made creepypasta like the whole "Candle Cove" thing so powerful for a while was that morbid pirate stuff IS kid fodder, but it's a bit off to see it being aimed at the age it was directed at and stylized quite that way.
Ah well, I'm in an odd mood, and probably overthinking this. It's very cool, but at the same time makes me think it's a bit odd. I think the other options would have been more appropriate to be honest, but well... it was the kid's choice. I can see why he likes pirates with the stuff out there right now, it does make me wonder what's going to happen if he ever learns much about pirates for real. Captain Cook, John Teach, and others were all hardly nice people.
