The Transforming rabbit is a rabbit that can transform into a silk top hat at will. It is fat and white in its rabbit form and is made of black silk in its hat form.
Behind the scenes
- It is unknown whether this is an entirely different species, or just a normal rabbit enchanted to transform. The former is most likely, as the rabbit is transforming at will, and so must have some magical ability.
- The creature is a reminiscent of the Muggle trick in which a magician pulls a rabbit out of a top hat. It is unknown whether the rabbit is the only one of its kind or if there are others.
