Hello! My Name is ChiChi the Chihuahua and this is my story........ Once Upon a time.......
One day in a land full of unicorns and puppies named Fairyland, there came a hideous purple beast, who came crashing a terrorizing the land. He stole all the candy and magical potions in the castle.
As soon as ChiChi the Chihuahua heard about this terrible news, she ran as fast as she could to the candy factory, which was where the monster was at.
Im going to kill him for what he has done to our kingdom!!!
When the hideous monster started to see ChiChi the Chihuahua, his big jaw dropped and he was very, very scared of this little puppy because of how colorful she was. He was also scared because every time he sees a rainbow or something colorful he faints.
So when ChiChi the Chihuahua turned around and started to change color again and again, the monster fainted. He was later on taken to the dungeon for the rest of his life.
So in this case, ChiChi the Chihuahua is considered the a "survivor of the fittest" in this environment because her colorful fur has scared the monster!
