If you were with us for the EDGE contest awhile back then this should come as no shock to you, but that doesn't make it any less cool.
Joystiq has issued a challenge for their readers to solve a level in Scribblenauts. There's no prizes this time around (except for the accomplishment of a job well done!) nor is the level particularly difficult. You can see the level and what it entails at the top of this post.
However, despite not being very hard, this sure sounds like it could be a ton of fun and allow for creative (and entirely insane) ideas. The lack of a challenge will enable some really awesome and free form solutions...at least I hope. We're not sure what "cheating" means, but I assume you can't just walk over to it and knock it down. Still, it just said no guns. Explosives? Nukes? A black hole? Those are entirely different stories.
So head over to Joystiq and drop them a comment. They'll have the results on Monday.
