When Timmy wishes that his Imaginary Friend Gary was real, Imaginary Gary is instantly favored by Timmy's friends, family, and even Trixie. Later, however, it turns out that Gary wants revenge for Timmy abandoning him for real friends. Timmy cannot even unwish him because Gary is from his imagination, and thus is a part of him, allowing Gary to make wishes, too.

Timmy, tired of Mr. Crocker's constant pop quizzes (in which he asks a question that no one can answer, or does not give enough time for people to answer), which everyone fails, wishes that he had mind reading powers. He uses this to pass Crocker's pop quizzes and mess with his friends' heads. Unfortunately, Crocker figures his wish out, and uses an anti-mind reading helmet (which causes someone trying to read the mind of the wearer to read their own mind instead) as part of a new plot to capture his fairies.
