Otherland 2: River of Blue Fire, Tad Williams

    From this book I'll never forget that cartoonish simworld that had the dancing vegetables and fighting utensils.  There was also a pirate ship that sailed on a river meandering through a gigantic kitchen floor, the source of which turned out to be ice cubes melting high up in a freezer, spawning a waterfall that fell the entire length of the refrigerator.  Orlando and Sam were the heroes in this simworld; they had to face the pirates and animated food-army that was trying to kill them. Otherland is so out there and creative that you can almost think up your own simworlds and imagine they exist inside Tad William's versatile creation.
