Fever Fudge is a type of sweet made by Fred and George Weasley for their Skiving Snackbox. Fever Fudge is designed to make the one who eats it get a high fever within seconds of eating it, but the side effects are large, pus filled boils, which appear at places that the twins don't "generally display to the public", and they make "sitting on a broom a right pain in the" said place. These boils may be eliminated with some Murtlap Essence.
In the 1995–1996 school year, while the twins were still at school, this is one of the many Skiving Snackbox sweet variety they have sold and tested on students, and they were used to allow students to skip classes, but mainly as part of the Umbridge-itis disease to annoy the tyrannical Dolores Umbridge.
Behind the scenes
- In the film adaptation of Harry Potter and the Order of the Phoenix, Fred and George drug Argus Filch with chocolates that might have contained Fever Fudge, as he is shown in Umbridge's office with large, pus-filled boils on his face. Although, displayed in one scene of the fifth film, there was a student with pus filled boils on his face. Fever fudge symptoms were seen on another student not long after. Therefore, the candy used to drug Argus Filch may have been a different candy.
