Forbidden Island

We have a fun cooperative game we like called Forbidden Island. The premise of the game is that the players are a group of fortune hunters who have landed on an island with four treasures. The island has been enchanted (or something) to protect the treasures. Throughout the game, the island sinks. The players try to grab the treasures and get out of there before they are trapped on the sinking island. Either everyone escapes and wins or everyone loses.

I knew the kids liked the game, but I was still surprised when they made their own pretend version of it one summer afternoon. Each blanket and pillow was a piece of the island. Sometimes they'd sink and have to be fixed. Sometimes they'd sink and be gone forever. Sometimes they'd move. The kids jumped around from place to place doing whatever it was they had decided was their goal. They stayed busy for quite a while that afternoon.
