- Argus Filch: "What are you doing?"
- Harry Potter: "Nothing."
- Argus Filch: "Nothing! A likely story! Sneaking around on your own -- why aren't you in Hogsmeade buying Stink Pellets and Belch Powder and Whizzing Worms like the rest of your nasty little friends?"
- — Filch grilling Harry about why he wasn't in Hogsmeade[src]
Stink Pellets are a joke product that presumably releases an unpleasant odour. They were sold in Diagon Alley in Gambol and Japes Wizarding Joke Shop, and in Hogsmeade, most likely at Zonko's Joke Shop. They are not tolerated by Argus Filch.
- "You filthy little beasts would never have dropped Stink Pellets if you'd known I had it in my power to whip you raw, would you, now?"
- —Argus Filch[src]
Early in the 1993-1994 school year, Fred Weasley was running low on these and wanted to get some in Hogsmeade. Their usage is similar to that of a Dungbomb, another item not tolerated by the Hogwarts caretaker.
In 1996, as the tyranny of Dolores Umbridge reached a new level with her becoming Headmistress, the students of Hogwarts revolted en masse, and Dungbombs and Stink Pellets were dropped in the halls with such frequency that it became the new fashion for students to use the Bubble-Head Charm just to ensure that they had a supply of fresh, clean air.
In 2020, Hermione Granger told Ron Weasley (actually Albus Potter with the use of Polyjuice Potion) that if he had left another stink pellet in her office, then he would be in big trouble ("Merlin won't help you").
Behind the scenes
- Mucus Projectum was a spell planned for the video game adaptation of Harry Potter and the Prisoner of Azkaban, but was cut from the final version of the game. It is possible that the spell would have a similar effect to the manner that Stink Pellets are used in the final game.
