The Wii U version of Scribblenauts Unlimited features a robust object editor. This means you can create your own objects and share them with your friends. Although, I’m not sure if turning the dark lord Cthulhu into a clown is a wise idea. He may tear open a door to another universe in the middle of your living room — his vengeance knows no bounds. Scribblenauts Unlimited comes out on November 18th along side the Wii U.
