Characters from Fairly OddParents have made appearances on Nickelodeon's Kids Choice Awards on 2003, 2009, 2010, and 2011.
Cosmo and Wanda were announcers for that year. In one part, they called a commercial break before announcing the winner of the burp off. Cosmo drank some soda and burped at Wanda, saying "I'm so going to win". Then, Wanda took it from him, drank some, and burped out fire at him. Amazed and burnt, he said "Wow, what have you been eating?".
The Kid Choice Awards held a burping contest with cartoon characters that year. For the FOP team, Poof did a very good burp while Timmy cheered for him. He eventually lost to Rico, from "The Penguins of Madagascar".
In 2010, KCA held an Ultimate Dance Smackdown. Poof and Foop, along some Nick stars, made a disco routine. They lost to Fanboy and Chum Chum's hip-hop routine, though.
In 2011, The Fairly OddParents, along with T.U.F.F. Puppy, participated at the Kids Choice Awards. Cosmo, Wanda, and Poof were seen in three dimensional CGI form, based on their appearance in the live action TV movie. They presented the award for Favorite Book to the Diary of a Wimpy Kid series.
