and Wanda Venus Fairywinkle Cosma are the married pair of fairy parents that are assigned to Timmy Turner. They are more like the smarter, caring parents Timmy never had. To keep themselves a secret, they usually masquerade as Timmy's pet goldfish and live in a magical castle inside of his fishbowl. Timmy is forbidden from revealing their existence, for the penalty is losing them for good. In Season 6, they had the first fairy baby in over 10,000 years, named Poof. It is also revealed in one episode that Cosmo is directly responsible for many historical tragedies, such as the volcanic eruption that destroyed the city of Pompeii, Italy and the sinking of Atlantis. He also destroyed Pluto in one episode. However, Wanda is responsible for the extinction of the dinosaurs, as revealed in the episode "Cosmo Con."
