How do you get passed the polar bear cage on Club Penguin?

You have to throw an O-Berry onto the lever that controls the water. Your puffle goes up to get it and turns on the water. Then place two more O-Berries strategically to guide your puffle to activate the big wheel that lifts the cage door.
