During a dueling competition in 1937, a wizard transformed himself into a bull, but was defeated by another wizard, who changed himself into a viper and bit the first wizard, thereby causing the bull-wizard to lose.
Behind the scenesEdit
- If a wizard completely transfigures himself into an animal, he starts thinking like the animal. It is likely that another wizard had to untransfigure him.
- In LEGO Harry Potter: Years 5-7, a bull was used to scare the Gringotts dragon instead of the Clankers.
