The 'key block'
The King Block
I would recommend Fantage. It is fun and safe and entertaining. If you don't want to talk on it you can activate something called Safe Mode where you can't speak unless you change it to normal. Club Penguin is good, although it gets boring. Moshi Monsters is another. Panfu is really fun however they are very strict so you could get banned for the tinest thing. Movie Star Planet is really good however you may want to stay clear of the forums and chat rooms as they can get very inappropriate, but it is great fun. I'm esmereld on Fantage. I don't really go on the others any more. Visit my Fantage blog at: platinumfantage.blogspot.com Ooops and I forgot Bin Weevils.
The top center block in an igloo is called the "keystone."

The keystone is typically larger than the other blocks and is carefully shaped to fit snugly into the apex of the igloo's dome.

It doesn't fall in because the blocks around it should have a slight bevel upward and the final piece should be cut to fit very snugly.
An igloo dweller is an Inuit or Eskimo.
In Inuktitut, an igloo is called "iglu."

There is a fire in the igloo that keeps the people living in it warm. The igloo is also made of a few layers of blocs of snow and ice so it can block the wind and cold weather from coming inside.
