The Igloo is the player's house on Club Penguin Rewritten. The player can customize it with furniture bought from the Better Igloos catalog with the Igloo Editor. You can buy new igloos and flooring in the Igloo Upgrades catalog. You can also play a variety of music. Igloos are where Puffles stay when not being walked and where all your furniture goes.
You can open your igloo up for anyone to go to or you can have it locked, where only you and your Buddies can enter.
Igloo Contests are frequently held. In these contests, penguins are given a theme, usually related to an ongoing Party or Event, to base the decoration of their igloos around, and can then submit their igloo to a panel of judges for the chance to win prizes. The first Igloo Contest, the Super Silly Igloo Contest, was held in conjunction with the April Fools' Party 2017 and began on March 31, 2017.
