Skeleton Party 2015

So I was doing some snooping around in the Club Penguin files when I found these:

The early, work-in-progress logo for the party.

Looks like some old party rooms will be reused!

What the Mine Shack will look like.

It seems that some more old places will be revisited...

Now this is REALLY weird. I wonder what this is for.

... oh, and it seems that a certain old enemy has returned, but are those ghost puffles?

Skip during this party. He's gotten quite the makeover, if I do say so myself! Kinda creepy, though.

An early, prototype version of Skip when you fight him. This must be the scariest thing I found; I think I can see bones on Skip!

So, yeah. Looks like this party's gonna be really creepy. It seems like this party might be the Halloween Party for this year, but among those pictures I found this other picture:

It appears to be Scorn, but white instead of black... and with different coloured eyes. Weird.

So, yeah. It looks like this apparent party is gonna have a few old enemies and places returning, but I can't seem to piece this all together. Obviously, it has something to do with skeletons but what? I'll have to dig deeper. Tell me what you guys think and I'll (hopefully) report back with more info later/tomorrow.

EDIT: So, uh, I was looking through the files again when I found this little picture called "prtbthrbtskltnsntchr" but because that name was way too confusing I decided to rename it after what it is. Anyway, take a little look at it and discuss and I'll report more tomorrow:

Boy, I bet this'd be a real challenge to fight. After all, do you see that tiny green thing to the side? That's a penguin.

The Snow Forts during this party. Pretty spooky, but what's that thing at the top of the screen?

also APRIL FOO- oh wait it's not april fools anymore

oops
