Teapot to tortoise

Teapot to tortoise is a Transforming spell. Third years at Hogwarts School of Witchcraft and Wizardry were required to cast the spell during their final exams. If the spell was not performed perfectly, the tortoise may breathe steam, have spouts where the tail should be, or have the teapot's willow-pattern on their shell. Hermione Granger worried that her tortoise looked more like a turtle, much to everyone else's annoyance since many other students had their tortoises breathe steam and have other weird traits.
