The upcoming Wii U and 3DS versions of Scribblenauts Unlimited may draw from Nintendo's well and bring the company's iconic characters into the game, according to an image that first appeared on GameStop's Facebook page.
Earlier today, GameStop posted an image (above, top) of the game's protagonist, Maxwell, standing between silhouettes and under neath text that read: "Guess who's playing with Maxwell? Find out October 17th."
Later in the day, a guess from commentator in a Kotaku comment thread (above, bottom) showed Yoski, Peach, Luigi, and Mario as seen in their Paper Mario above the left silhouette. Above the right silhouette are Epona, Link, Zelda, and a Goron.
