The Pharaoh Hat was a puffle hat in Club Penguin. To get this puffle hat, you had to buy the blue puffle with the pharaoh hat. You had to use the code given when you have purchased a blue puffle plush. When unlocking, you would get coins, a Pharaoh Hat, and an item of choice from the Treasure Book.
These are the reactions puffles give when the player selects this item from the interface. Reactions have no purpose beyond the following visual effects:
If they dislike it, they will lower one eyebrow and purse their lips.
If they are neutral towards it, they will look up, curiously.
If they like it, they will jump up and down, but make an exasperated face if the player de-selects the item without giving it to them.
