Emotions are a feature which is available in all of the games. Emotions appear above NPCs when they have a certain emotion towards something. Sometimes emotions are displayed when an object sees another object. In other cases, objects will display a certain emotion related to any adjectives that they may possess. For instance, an object with an adjective that affects its value will display the "money" emotion.

Scribblenauts Unlimited and Scribblenauts Unmasked
With the addition of the Object Editor many emotions were added to the game, making the characters and objects much more expressive. There are 222 emotion in total in both Scribblenauts Unlimited and Scribblenauts Unmasked.
The reason Scribblenauts use emotions because the developers didn't want to have to make millions of different faces for each monster, person, animal, or inanamite object with a living adjective on it.
