It sounds like a meme.
What the heck 
Good morning
I thought tere was a new sneak peak buh
:l :) :D :DDDDDDDDDDD my fav hallowday budum kshh
Peak.
A new land 
Map expansion or new island?
what do ya guys think
Ooh a land expansion with spooky scary skeletons 
Oh just a normal day in CC2
wait WHAT THE FU--
New land is forming
My fog is coming
BTW this image is from Stormlend in a bug report. He speculates it is a sneak peek for the Halloween event, reasoning being that it’s huge and looks out of place
and I agree
Looks like an assimilation from the effects of the upcoming event
Since halloween events usually are spooky themed with similar type of terrain texture, such as adding dead leaves
New island?? 
Prepare your weapons
Temporary expansion
I think so too, just like the leaked bridge
