Owlowiscious

Owlowiscious is a brown owl shown to be in the care of Twilight Sparkle in the show. Owlowiscious is generally shown helping Twilight Sparkle out with her late-night studies, due to him being nocturnal, thus allowing Spike to sleep. Owlowiscious is known for his hoot, "Who?", which causes frustration to those who try to communicate to him. Fan works have shown many characters, both official and OC's, falling for this trick. When he recives a more sentient personality, he is generally depicted as the "wise owl", sharing Twilight's love of books and having great knowledge.

Owlowiscious appears in many fan works starring Twilight and Spike, usually confusing someone with his "Who?", as in Turnabout Storm, where he tricks Phoenix Wright.
