If "SHAKE" button in the corner of the igloo was clicked, the whole igloo would shake, and the snowflakes on the floor would instantly appear in mid-air and slowly fall back to the floor.
The original sprite of this igloo had a hatch door in the center of the floor. It was never visible on the in-game sprite due to code preventing it from appearing; however, the December 2006 Igloo Upgrades catalog displayed this igloo with the door, both on the cover, and the page where it could be bought. The door was removed a few days after this igloo's release, both from its sprite and the catalog. The door did not function as a typical igloo door (which would typically cause the map to appear when clicked) and was merely visual.
