2016 Birthday event

The third birthday involved searching for the gnome child's lost hat.
 * 1) Speak to the gnome child in the front of Lumbridge Castle and learn that he has lost his hat.
 * 2) Speak to Hans around Lumbridge Castle, who advised he saw a seagull carry away the green hat, but could not advise of the direction in which the seagull flew.
 * 3) Travel to Port Sarim and speak to Captain Tobias, Seaman Lorris, or Seaman Thresnor. The player would be told they saw a man in white armor wearing the hat being described.
 * 4) Go to Falador Park and speak to Sir Tiffy Cashien to receive a present intended for his grandson's birthday.
 * 5) Speak to the gnome child again, who has by this time already found his hat. He engages in a dialog reminiscent of Schrodinger's cat. The hat is both inside the box and not in the box, until it is opened and observed.
 * 6) Open the present which contains a gnome child hat. If players did not obtain the birthday event items from previous years, they will receive it along with the hat.
 * 7) Optional - return to Sir Tiffy, talk to him, and find that his grandson also received the hat and is happy.
