The Mega Whale, also known as the Inflatable Whale or The Party, was added on June 13, 2008 during the Summer Kick Off Water Party. It is at the left of the Iceberg. The Tour Guide briefing on the place goes as follows: "Welcome to the Inflatable Whale! This room was added just for the party. Look out for the spray!". This room is simply a big, blue, and inflatable whale that floats on the water. Penguins can walk all over the whale.
It has been on maps of Club Penguin. It was shut down on June 18, 2008.
