I'm making Scribblenauts in Scratch... but it'll be hard to add all 20000+ objects, right?.... Nope! If lots of people contribute to this project, this could get done in a week!
:D Don't just import images Just remember to make it easily scaleable-using outlines will make it harder, unless you just use one size of outline. Also, DO NOT make this in your own style-try and make the objects as accurate as possible.
