Human to pig

"Shouldn'ta lost me temper, but it didn't work, anyway. Meant ter turn him into a pig, but I suppose he was so much like a pig anyway there wasn't much left ter do."

- Rubeus Hagrid on his attempt to turn Dudley Dursley into a pig

This spell was used to transform a human target into a pig. It produced a flash of violet light when cast.

In 1991, Rubeus Hagrid attempted to cast this spell on Dudley Dursley, but it did not work as intended, only giving Dudley a curly tail that poked through his trousers. This was presumably due to the fact that Hagrid used a broken wand, and, having been expelled from Hogwarts in his third year, was not a fully-trained wizard. However, Hagrid claimed that, because Dudley was already "so much like a pig", all he needed was a tail. It is unknown if that is the actual reason but it most likely is not.

Circe may have used this spell to turn sailors into pigs in ancient Greece.
