Deej is actually only give a few hours of sunshine along with a McDonalds kids meal each day. The water was his special treat. A change from the flat day old soda they give him. In his dark and cold cellar, they force him to write terrible, cringeworthy puns on paper by the glow of his daily glow stick. He only gets one a day. If he doesn't complete his task, they replace the burger buns with sandpaper and they place a few live spiders in the HappyMeal box.
