5TH Cell's Scribblenauts is an amazing piece of E3 award-winning game design, letting the player summon almost anything they can think to write on the Nintendo DS touchscreen. Despite being rated "Everyone 10+" the game features some potentially objectionable content.
Perhaps most objectionable are the things one can do in Scribblenauts when babies, steak and lions come together, as amusingly described by the Entertainment Software Ratings Board. Warning: gruesome descriptions of rad bike tricks performed over infants await you! Proceed with caution.
