A wizard who lodged a complaint with the International Confederation of Wizards about the Uagadou School Animagi Team. Their performance of “synchronized transforming” astounded the crowd attending an International Symposium of Animagi. Many older wizards, including Mr. Tutley, “felt threatened by fourteen-year-olds who could turn at will into elephants and cheetahs.” Adrian Tutley is an Animagus himself who can transform into a gerbil.
While the name reveals little, the fact that Adrian turns into a gerbil, a tiny nervous rodent, suggests something about his personality. It is not surprising that he was frightened by young teenagers turning into ferocious beasts.
