All right. This seems hard to explain but really easy. OK, open your player card. Take all clothes off. CLOSE THE PLAYER CARD. Open it again. Now choose an item that does a special dance like the hard hat or water wings. DO NOT CLOSE THE PLAYER CARD. Click on someone else and then exit their player card. start dancing and you will do the special dance without the Special Clothes.

The new pin is green tent and is outside of the mine.

The iceberg can be tipped. You need 100 penguins in one corner of the ice berg moving (I suggest dancing or jack hammering (the hard-hat is no longer available))

There are 3 items hidden in the clothing catalogs. Currently there is the red electric guitar (hidden on the electric guitar), Viking helmet (hidden on the headphones), and the Swim Goggles (hidden on the wet suit).
