To play this game, appoint one player to be the Pirate.
Have the kids form a circle around the Pirate. Give them a key. Put on some music and tell the Pirate to close his eyes. While his eyes are closed, the kids pass the key around the circle.
At some point, stop the music. When the music stops, the kid holding the key must hide it, and the Pirate has to try and guess who has his key. If he guesses correctly, the kid holding the key becomes the new Pirate.
If he guesses incorrectly, he has to be the Pirate again,
If they guess wrong 3 times then switch out the players, so everyone gets a turn at being the Pirate.
