10) Make the pirate say "Arr-gh" as you cream him

You’ll have to do a whole lot of swimming to find the sunken pirate ship in the middle of the sea (check your map and look out for the handy ship-shaped blob near the island). Once there, you’ll meet this young pirate who instantly tries to brain you with a stick. Dodge his attacks and kick his peg-legged ass, and you’ll win his garish seafarer headwear. It’ll be all the rage in Milan next year, darling.
