In Don't Rock the Boat, players must balance their pirate penguins on the ship without making it tip. Balance the boat on top of the water piece. Then, have each player take four pirate penguins. The first player places a penguin on the ship. Moving to the left, each player takes turns putting one penguin on the ship at a time. Players can place their penguins on the ship wherever they want, but they can't rock the boat. When someone rocks the boat and one or more penguins fall overboard, that ends the game. The last player who placed a penguin on the ship before the player who rocked the boat wins. The game comes with a ship with three masts, a two-piece water wave, and 16 pirate penguins. It is for two to four players.
