There are 8 unique characters that are full of fun, showing a mini-performance to express one of the 9 emotions. They're acting like cartoon characters - you just have to see it! Cowboy and gangster, blonde and brunette will behave differently to express emotions. A shy gangster? A kissing blonde? Try them all out - it's lots of fun!
