Little Willy is the nephew of groundskeeper Fiddlesworth and a possible resident of Ghoulhaven Hall. He is mentioned several times in the game and is the owner of the Holy Water Squirter which Fiddlesworth lends to Cooper to fight Zombies, though it's likely that Willy only uses the gun as a toy. It's unknown if he lives in the mansion. Considering that Fiddlesworth lives in a cottage at Ghoulhaven and that Little Willy was mentioned being treated in the house's Infirmary for an eye infection, it's likely he does. Despite being mentioned often by Fiddlesworth, he is never seen in the game.
