D.W.

Dora Winifred (prefers being called D.W.) is Arthur's little sister and an antagonist in Arthur's Nightmare.

Behavior
D.W. becomes a threat on Night 3. She slowly rises out of a hole in the ground located in every room. If the player stays in the same room for too long and D.W. fully enters the room, she will shout, "Hey!" and kill the player. Playing safe and waiting for Arthur to move to a room where he can't catch you can be a problem. Searching all places in a room can also be a problem, if the room has many places to search, like the Kitchen. When the player collects 6 Woogles, D.W. rises quicker. If the player leaves the room before D.W. gets out, she will move to the next room and restart the cycle all over again. She also looks the same from her T.V show appearance only with a circle mouth with pointed teeth and red eyes. She is creepy because of her eyes and mouth

Trivia
Upon killing the player, D.W. will shout "Hey!" This is the same scream from the theme song of the TV show when Arthur appears onscreen, the scream making him fall backwards.
