Funko Pop! Harry Potter: Ron Puking Slugs with Bucket

The Slug-vomiting Charm (Slugulus Eructo) was a curse, that forced the victim to burp up slugs. They may also have taken on a sallow complexion as a side-effect. It was described as a green jet of light. Treacle fudge can cure the effects in a few seconds, although it will eventually wear off on its own.
