He forgot food and water but fortunately he still has the pocket from when he adventured with syk.  He opens the book to check again.  The map shows an entrance but a visual inspection reveals an empty room.  He pulls a Snickers bar out of his pocklet and unwraps it.  He discards the wrapper in a trash receptacle just below a<strong>Keep Our Gingerbread House Clean</strong>sign.  He eats the candy bar as he peruses the scene.
