I think I may try to do the Pirate "arrrrr" sound so it goes with the Pirate icon.

Unfortunately all the Pirate sounds on the web I came across seem to cost real-life money, so i may have to try and create it myself. The horror!

Alternatively, I do have a clip of a Zombie going "brainzzz" which would be fun to use if I updated to icon to the zombie. LOL.

EDIT: My co-worker just helped me out with recording an ARrrrr on iPhone, so I'm all set with that lol. Good use of work time.
