Hermione Granger studying this spell from Intermediate Transfiguration[src]

This spell could be used to transform an owl into a pair of opera glasses.[1]


It was covered in Intermediate Transfiguration, a book studying transfiguration; a series of diagrams helped readers understand the spell.[1]

Hermione Granger read about this transfiguration while studying for her Ordinary Wizarding Level examinations in May of 1996 while discussing Professor Hagrid's request that they train his giant brother Grawp how to talk.[1]
