Timmy and Wanda share a special relationship that he and Cosmo lack. Although Timmy and Cosmo are more along the lines of buddies, Wanda acts more responsible and like a mother figure to Timmy, to protect him from danger and (trying) to prevent him from making stupid decisions and wishes. Although Timmy sometimes overlooks Wanda's advice, he is never really surprised when it turns out she was right all along, and will usually take her advice over Cosmo's unless her husband's idea sounds more fun-structive. Despite said dumb actions, in Hassle in the Castle she risked being transformed to protect Timmy and Cosmo, who were ducks.
