Monkey Butt language

Monkey Butt language is a language used by Rainbow-butted Fruit Monkeys and other creatures that have rainbow butts. It is spoken by changing the color of the butt.

Examples of the language

 * Blue - sad
 * Red - angry
 * Pink - happy
 * Orange - pizza

Grammar
A word can be an opinion about what someone else means, as shown on this example:


 * Creature 1 has a blue butt (sad) and Creature 2 changes their butt to pink (happy). This means Creature 2 is happy that Creature 1 is sad.

Orange (pizza) can mean just the word "pizza", or something like "I want more pizza".

Trivia

 * Fred owns a book that helps him understand this language, called "How to speak Monkey Butt".
 * When a rainbow-butted creature is not talking, the butt just flashes between colors.
