According to an Amazon.com listing, the follow-up to the million-unit selling Scribblenauts will be titled, "Super Scribblenauts".
The listing has now been removed, but the URL for the game clearly shows the game's name.
A Scribblenauts sequel was announced back in March, with the promise that players will have the ability to write any object that comes to mind and modify it in any way they desire using adjectives.
It was also revealed that the game will feature 10,000 new words, 120 new and improved levels and an enhanced level editor. Sounds super.
