It seems that the Wii U version of the upcoming Scribblenauts Unlimited will include characters from both the Mario and Zelda series.  Promotional artwork shows Mario, Luigi, Peach, and Yoshi hanging out with Scribblenauts protagonist Maxwell as well as with a few other Nintendo friends (Link, Zelda, Epona and a Goron.)  Sadly, it appears that the Nintendo characters can't be modified in any way, unlike nearly everything else in the game.

More details to come later, we assume.
