From time to time, those of us with way too much time on our hands like to peruse (see: troll) the ESRB's Web site for whatever information we can find. This comes in the form of XBLA/PSN games being revealed early, plot spoilers, and the occasional hilarious rating summary.
"If multiple words are entered in a sequence, different whimsical scenarios can be triggered: a bicycle can be used to jump over a baby; a bulldozer can clear away a shark; and cabbage can be fed to dinosaurs."
Continuing, the ESRB makes it clear that "These types of items can be used to destroy objects or even other summoned items (e.g., a club can be used to hit an animal; steak can be attached to a baby to attract lions; rockets can be lobbed at a man)."
"If players wish to, they may type in the word vomit, which causes a beige-colored lump to appear on the screen." Oh the humanity! Won't someone think of the children?
