Scribblenauts is currently involved in a racism scandal, as the word "sambo" is featured in the game. If you type the word in a fruit that looks like a watermelon appears. Some people have claimed that the game is being racist because the word is in there at all, while others claim the game is being racist because "sambo" is an old derogatory word for black people, and one stereotype is that all black people like watermelon. The truth from the Scribblenauts team, however, is the fact that sambo is a watermelon looking gourd/fruit and that's why it appears as it does in the game and why it was included.

Destructoid has more on the subject and the history of sambo and why some people are offended.
