Gossack

Gossack appears in The Wind Waker, where he can be found in the Cafe Bar on Windfall Island. In order to obtain the Deluxe Pictobox, Link has to take a picture of Gossack displaying fear. To do this, Link can roll into the wall near Gossack, throw a pot at him, or smash some cups in the café to scare him.

Trivia

 * In Skyward Sword, there's an old woman that resembles Gossack, situated in the kitchen of the Knight Academy. Not only does she look similar, but she also displays the same fear as Gossack when Link breaks a pot near her.
