Speculation is sometimes used to fill in the blanks in in article. Other than the main characters, very little is known about most characters in The Fairly OddParents universe, even characters that have been regularly appearing since the first season. Sometimes information that is revealed about a character is ret-conned from the canon, which can cause a lot of confusion.
Avoiding speculation[]
Articles should contain as little speculation as possible. Any information about a character that is included in an article should have a dialogue from an episode that supports it. Using citations also helps improve the credibility of an article.
Speculation tag[]
If an article is based on nothing but speculation, or includes mostly information that is speculation, and the contents of which do not have anything in the show that supports what is written, then that article should have the {{Speculation}} tag placed at the top of the article.
