Here some more sneak-peek images for the Adventure Party 2012 thanks to Trainman1405 for these images.
The Night Club:
The Snow Forts:
Inside the Snow Forts room: (note the dates)
The top of that room: (appease the volcano?)
As you can see in the images there is a lot of free headdresses and I think there will be a scavenger hunt because at the Forest there is a Apple looking pin or icon, a Watermelon at the Dock and a Pineapple at the Cove.
